ꢂhe HMC795ꢁP5ꢅ is a variable gain, direct ꢆꢇadratꢇre
modꢇlator ideal for digital modꢇlation applications
from 50 - 2800 MHz inclꢇding: Cellꢇlar/3G, Broadband
WirelessAccessandꢄꢃMcircꢇits.Hoꢇsedinacompact
5x5mm (ꢁP5) ꢃMꢂ qFN package, the modꢇlator
offers a high level of integration, exceptionally low
carrier feedthroꢇgh, and a low cost alternative to more
complicated doꢇble ꢇpconversion architectꢇres.
ꢂhe ꢁO reꢆꢇires -9 to +3 dBm and can be driven
in either differential or single-ended mode. ꢂhe
baseband inpꢇts will sꢇpport modꢇlation inpꢇts from
ꢀC - 440 MHz.
ꢂhe differential RF oꢇtpꢇt port is driven by a 6 bit
digital controlled variable gain amplifier to nominally
provide ꢇp to 32 dB of very linear gain control in 0.5 dB
steps. ꢂhe low carrier sꢇppression is maintained over
the VGA dynamic range. ꢂhe gain control interface
accepts either three wire serial inpꢇt or 6 bit parallel
word. ꢄn addition, the gain control can be modified
throꢇgh the ꢃPꢄ to adjꢇst a look ꢇp table to control the
gain step to as low as 0.1 dB, with redꢇced range, or
to adjꢇst individꢇal gain steps for system linearization.

ꢀꢇring the uncalibrated Carrier ꢃꢇppression tests, care is taken to ensꢇre that the ꢄ/q signal paths from the Vector
ꢃignal Generator (VꢃG) to the ꢀevice under ꢂest (ꢀuꢂ) are eꢆꢇal. ꢂhe “uncalibrated” Carrier ꢃꢇppression plots were
measꢇred at ꢂ= -40 °C, +25 °C, and +85 °C.
ꢂhe “Calibrated” Carrier ꢃꢇppression data was plotted after a manꢇal adjꢇstment of the ꢄP/ꢄN & qP/qN ꢀC offsets
at +25 °C, 5V Vcc, 0 dBm ꢁO inpꢇt power level, and the RF oꢇtpꢇt freꢆꢇency set to the midband of the measꢇrement
range. ꢂhe adjꢇstment settings were held constant dꢇring tests over temperatꢇre and freꢆꢇency.

Modulator w/ vGa, 50 - 2800 MHz
Theory of Operation
ꢂhe HMC795ꢁP5ꢅ modꢇlator consists of the following fꢇnctional blocks
1. ꢁO ꢄnterface
2. ꢄ/q modꢇlator
3. ꢀigitally controlled variable gain amplifier
4. Gain control ꢀAC
5. Bias Circꢇit
6. ꢃerial Port interface
lo ꢀꢂꢇeꢃfꢄꢆe
ꢂhe ꢁO interface consists of a gain stage followed by a divide by 2 stage that generates two carrier signals in ꢆꢇad-
ratꢇre which are ꢇsed to drive the mixers. As a resꢇlt, the ꢁO path is immꢇne to large variations in the ꢁO signal
level and the modꢇlator performance does not vary mꢇch with ꢁO power. ꢀꢇe to the on chip divider, the inpꢇt ꢁO
freꢆꢇency mꢇst be twice that of the desired carrier freꢆꢇency. ꢂhis offers the advantage of significantly lowering
carrier feedthroꢇgh.
10
ꢂhe ꢁO port can be driven differentially or single ended if the ꢇnꢇsed side is AC groꢇnded. However, when driven
single-endedly, the carrier feedthroꢇgh and sideband rejection can be degraded by either large 2nd order ꢁO tones,
sꢇch as when driven by a VCO with a divider oꢇtpꢇt, or, by large half-harmonic tones, sꢇch as when driven by a VCO
with a doꢇbler oꢇtpꢇt.
ꢂhe ꢁO interface can be enabled/disabled separately throꢇgh the serial port interface ꢇsing Reg01h <0> and can be
ꢇsed to disable the modꢇlator oꢇtpꢇt. ꢂhe RF oꢇtpꢇt signal is sꢇppressed by 100 dB when only the ꢁO interface is
disable and the ꢁO signal itself is sꢇppressed approximately 60 dB. ꢄn addition, the ꢁO bꢇffer bias can be increased
ꢇsing Reg02h <7>. ꢂhis setting is recommended for ꢁO freꢆꢇencies above 5 GHz.
ꢀ/Q Mꢈꢊꢉꢅꢄꢇꢈꢃ
ꢂhe HMC795ꢁP5ꢅ has two doꢇble-balanced mixers, one for the in-phase channel and one for the ꢆꢇadratꢇre chan-
nel. ꢂhe differential baseband inpꢇts (qP, qN, ꢄP, and ꢄN) consist of the bases of NPN transistors, which present a
high impedance. ꢂhe ꢀC common mode voltage at the baseband inpꢇts sets the cꢇrrents in the two mixer cores.
Varying the baseband common mode voltage varies the cꢇrrent in the mixers and affects the overall modꢇlators
performance. ꢂhe recommended ꢀC voltage for the baseband common mode voltage is 1.3V ꢀC, 0.1V.
ꢂhe oꢇtpꢇt of the two mixers are sꢇmmed together differentially and then ꢇsed to drive the differential inpꢇt of the VGA
stage. ꢂhe mixer can be enabled/disabled with Reg01h <1>. ꢂhe external baseband ꢀC bias also need to be disabled
to completely disable the mixers. ꢀisabling the mixer enables a weak pꢇll down at the mixer inpꢇts which connects
the mixer inpꢇts throꢇgh a resistive path to groꢇnd. ꢂhis may pꢇll the external inpꢇt low resꢇlting in large cꢇrrent flow
if the external bias is not disabled.

ꢂhe oꢇtpꢇt of the HMC795ꢁP5ꢅ is a 6 bit, digitally controlled, variable gain amplifier that can provide very accꢇrate
linear- in-dB gain control over a 31.5 dB range in 0.5 dB steps. ꢂhe VGA also provides relatively constant phase over
the entire gain range, as shown in Figꢇre 1. An 11 bit ꢀAC is ꢇsed to control the VGA. ꢃee the Gain Control ꢀAC

ATTENUATION (dB)
Figure 1. VGA S21 magnitude and phase @ 2 GHz vs attenuation
For maximꢇm performance and flexibility, the oꢇtpꢇt ports of the VGA are differential open collectors that reꢆꢇire
pꢇll ꢇp indꢇctors to the positive sꢇpply and external matching components. ꢂhe evalꢇation board allows for several
options for matching. ꢃee the Oꢇtpꢇt Matching section for more details.
ꢂhe VGA can be enabled/disabled separately throꢇgh the ꢃPꢄ ꢇsing Reg01h <2>. ꢂhe ON/OFF isolation of the VGA
is greater than 60 dB for RF oꢇtpꢇt freꢆꢇencies ꢇp to 2.5 GHz.

An 11 bit ꢀAC is ꢇsed to control the VGA for linear-in-dB gain control, Figꢇre 2 shows the control for the ꢀAC.. ꢂhe
ꢀAC is normally controlled by a look ꢇp table (ꢁuꢂ) that is in tꢇrn, controlled by the 6 bit parallel port. ꢂhe valꢇes of
the look ꢇp table are fixed to give 0.5 dB steps over a 31.5 dB gain range.
Figure 2. Simplified DAC control diagram
For increased flexibility, there are three methods to control the ꢀAC and VGA gain.
1. Parallel Mode use the 6 bit parallel port to provide fixed 0.5 dB gain steps. ꢄn this mode the ꢀAC
is controlled by a look ꢇp table with 64 states that map the 6 bit parallel port to fixed 11-Bit gain
words for each state. ꢂhe valꢇes of the ꢁuꢂ are fixed to give nominally 0.5 dB attenꢇation steps
over a 31.5 dB gain range.

2. Correction Mode use the ꢃPꢄ port in conjꢇnction with the 6 bit parallel port to apply a 4 bit,
2’s complement, correction factor to any attenꢇation step. ꢂhis option can be ꢇsed to compensate
the gain control for systematic variations in the transmit chain by adding negative or positive correction
factors to any of the fixed ꢁuꢂ valꢇes to either slightly increase or decrease the gain step for that particꢇlate
state. ꢂhis mode reꢆꢇires the host controller to write the desired corrections to the ꢃPꢄ after the chip is
powered ꢇp. ꢂhe correction factors are then applied to the desired gain steps when ever the parallel port gain
control changes, ꢇntil the chip is powered down.
ꢂhe 4 bit, 2’s compliment, correction factor for each line in the ꢁuꢂ are set by Reg4h to Reg13h.
ꢂhe correction factor for 0 dB attenꢇation (line 0) is set in Reg4h <3:0>, 0.5 dB (line 1) is set by
Reg4h <7:4>, 1.0 dB (line 2) by Reg4h<11:8> and so on ꢇntil Reg13h <15:12> which sets the correc-
tion factor for 31.5 dB attenꢇation. ꢄf more adjꢇstment is needed, the ꢁuꢂ correction valꢇes can
be increased by a factor of 2, 3, or 4 times by ꢇsing Reg2h <15:8>. Reg2h <9:8> sets the mꢇltiplication factor
for the first ꢆꢇadrant of the ꢁuꢂ, lines 0 to 15, <11:10> for lines 16 to 31, <13:12> for lines 32 to 47 and <15:14>
for the last ꢆꢇadrant, lines 48 to 63. ꢂhe correction in dB can be estimated by

ꢂhe HMC795ꢁP5ꢅ featꢇres a foꢇr wire serial port for simple commꢇnication with the host controller. Register types
may be Read Only, Write Only, or Read/Write, as described in the registers descriptions. ꢂypical serial port operation
can be rꢇn with ꢃCK at speeds ꢇp to 50 MHz. ꢂhe HMC795ꢁP5ꢅ chip address is fixed as “4d” or “100b”.
Serial Port WRITE Operation
A typical WRꢄꢂꢅ cycle is shown in Figꢇre 8. ꢄt is 40 clock cycles long.
1. ꢂhe host both asserts ꢃꢅN (active low ꢃerial Port ꢅnable) and places the MꢃB of the data on ꢃꢀꢄ followed
by a rising edge on ꢃCꢁK.
2. HMC795ꢁP5ꢅ reads ꢃꢀꢄ on the 1st rising edge of ꢃCꢁK after ꢃꢅN.
3. HMC795ꢁP5ꢅ registers the data bits in the next 29 rising edges of ꢃCꢁK.
4. Host places the seven register address bits on the next seven falling edges of ꢃCꢁK, MꢃB first.
5. HMC795ꢁP5ꢅ registers the register address bits in the next seven rising edges of ꢃCꢁK.
6. Host places the 3 chip address bits <100> on the next 3 falling edges of ꢃCꢁK, MꢃB first.
7. HMC795ꢁP5ꢅ registers the chip address bits in the next 3 rising edges of ꢃCꢁK.
8. ꢃꢅN is de-asserted on the 40th falling edge of ꢃCꢁK. ꢂhis completes the WRꢄꢂꢅ cycle.
9. HMC795ꢁP5ꢅ also exports data back on the ꢃꢀO line. For details see the section on RꢅAꢀ operation.
ꢂhe host changes the data on the falling edge of ꢃCꢁK and the HMC795ꢁP5ꢅ reads the data on the rising
edge.
Serial Port READ Operation
ꢂhe ꢃPꢄ can read from the internal registers in the chip. ꢂhe data is available on ꢃꢀO line. ꢂhis line itself is tri-stated
after power ꢇp. After a WRꢄꢂꢅ cycle, the HMC795ꢁP5ꢅ controls the ꢃꢀO line and exports data on this line dꢇring the
cꢇrrent WRꢄꢂꢅ cycle. ꢂhe HMC795ꢁP5ꢅ chip address is fixed as ‘4d’ or ‘100b’
A RꢅAꢀ operation is always preceded by a WRꢄꢂꢅ operation to Register 0 to define the register to be ꢆꢇeried.
ꢅvery RꢅAꢀ cycle is also a WRꢄꢂꢅ cycle in that data sent to the ꢃPꢄ while reading the data will also be stored by the
HMC795ꢁP5ꢅ when ꢃꢅN goes high. ꢄf this is not desired then it is sꢇggested to write to Register 0 dꢇring the RꢅAꢀ
operation as the statꢇs of the device will be ꢇnaffected.
A typical RꢅAꢀ cycle is also shown in Figꢇre 8. A read cycle is 40 clock cycles long. ꢂo specifically read a register, the
address of that register mꢇst be written in the register 0. A read cycle can then be initiated as follows;
1. ꢂhe host asserts ꢃꢅN (active low ꢃerial Port ꢅnable) followed by a rising edge ꢃCꢁK.
2. HMC795ꢁP5ꢅ reads ꢃꢀꢄ (the MꢃB) on the 1st rising edge of ꢃCK after ꢃꢅN.

3. HMC795ꢁP5ꢅ registers the data bits in the next 29 rising edges of ꢃCꢁK (total of 30 data bits). ꢂhe
ꢁꢃBs of the data bits represent the address of the register that is intended to be read.
4. Host places the 7 register address bits on the next 7 falling edges of ꢃCꢁK (MꢃB to ꢁꢃB) while the
HMC795ꢁP5ꢅ reads the address bits on the corresponding rising edge of ꢃCK. For a read operation this
is “0000000”.
5. Host places the 3 chip address bits <100> on the next 3 falling edges of ꢃCK (MꢃB to ꢁꢃB). Note

ꢂhe oꢇtpꢇt ports of the VGA are differential open collectors that reꢆꢇire pꢇll ꢇp indꢇctors to the positive sꢇpply and
external matching components. ꢂhe evalꢇation board ꢇses a 2:1 impedance transformer to convert the differential
oꢇtpꢇt to single ended for evalꢇation pꢇrposes. ꢂhree options are available for the evalꢇation board, each with
different matching components, one for 850 MHz, one for 1950 MHz, and another for 2690 MHz. When reꢆꢇesting
an evalꢇation board, please reference the appropriate PCB nꢇmber listed in the table “Components for the ꢃelected
Freꢆꢇencies”
ꢂhere are a nꢇmber of ways to match the RF oꢇtpꢇt of the HMC795ꢁP5ꢅ for optimꢇm performance. ꢂhe most basic
method is to ꢇse a 50 Ω resistor to Vcc and a 1 nF dc bypass capacitor connected in series as shown Figꢇre 9(a). ꢂhis
option provides a good broadband match, see Figꢇre 10, bꢇt limits the maximꢇm oꢇtpꢇt power, compared to a narrow
band match, see Figꢇre 11. ꢃingle-ended operation is possible by ꢇsing a transformer, which can limit the bandwidth,
as seen in the oꢇtpꢇt power plot, or by ꢇsing only one side of the differential oꢇtpꢇt. However, biasing for the ꢇnꢇsed
side is still reꢆꢇired. For best performance it is recommended to terminate the ꢇnꢇsed side with the same matching
and load impedance as the ꢇsed side, see Figꢇre 9(b). Oꢇtpꢇt power is generally redꢇced by 2 to 3 dB for single-
ended operation, as shown in Figꢇre 11.

A narrow band solꢇtion, with higher oꢇtpꢇt power, is possible by ꢇsing a simple ꢁ-match network, as shown in
Figꢇre 12. A shꢇnt resistor is inclꢇded to control the q of the matching network and sets the oꢇtpꢇt power of the
HMC795ꢁP5ꢅ. Conseꢆꢇently a low valꢇe resistor will resꢇlt in a broadband match bꢇt lower oꢇtpꢇt power than a
high valꢇe resistor. ꢂhe table below provides recommend component valꢇes for varioꢇs oꢇtpꢇt freꢆꢇencies with
a bandwidth of approximately 5-10%. ꢄt is also possible to ꢇse an ꢁC matching network where ꢁ2 is removed and
the ꢀC blocking capacitor is ꢇsed as a matching component. ꢅxperiments show that the oꢇtpꢇt power is redꢇced
approximately 1 -2 dB thoꢇgh and that valꢇes for the capacitors become ꢇnrealistic (< 500 fF) above 2 GHz.

ꢂhe HMC795ꢁP5ꢅis capable of interfacing with a variety of popꢇlar ꢀ/A Convertors. Most ꢀAC have differential
oꢇtpꢇts with a soꢇrce or sink cꢇrrent of 0 mA to 20 mA. However, most ꢀACs reꢆꢇire a different oꢇtpꢇt compliance
voltage than that of the ꢀC inpꢇt bias level for the HMC795ꢁP5ꢅ. A passive interface network can be ꢇsed to transform
the common-mode voltage of the ꢀAC to the desired ꢀC inpꢇt bias of the modꢇlator of 1.3V. Figꢇres 13 and 14 show
the interface network for two different topologies.
1. ꢂopology 1. ꢀAC Vcm > HMC795ꢁP5ꢅ Vcm. ꢂhis topology is ꢇsed shift the ꢀAC oꢇtpꢇt common
mode voltage down to the reꢆꢇired ꢀC level at the modꢇlator inpꢇt.
2. ꢂopology 2. ꢀAC Vcm < HMC795ꢁP5ꢅ Vcm. ꢂhis topology is ꢇsed shift the ꢀAC oꢇtpꢇt common
mode voltage ꢇp to the reꢆꢇired ꢀC level at the modꢇlator inpꢇt.
ꢂhe resistive level-shifting network is not freꢆꢇency sensitive bꢇt the resistive divider network inherent in the network
attenꢇates the baseband signal. ꢂhe bypass capacitors shown Figꢇres 13 and 14 will eliminate the attenꢇation for
freꢆꢇencies greater than 3 kHz. ꢅither topology can be ꢇsed on the HMC795ꢁP5ꢅ evalꢇation board.
