GENERAL DESCRIPTION
The HMC8362 is a gallium arsenide (GaAs), quadband,
monolithic microwave integrated circuit (MMIC), voltage
controlled oscillator (VCO) designed to offer wideband
capabilities without compromising on phase noise performance.
The device integrates four independent, narrow-band VCOs
with overlapping frequency bands, operating at a fundamental
frequency range of 11.90 GHz to 18.30 GHz. The consistent
tuning sensitivity across all frequency bands simplifies the
synthesizer loop filter design.
The HMC8362 integrates resonators, negative resistance
devices, and varactor diodes. The monolithic structure of the
oscillator offers very low phase noise, optimal temperature
stability, and is immune to vibration and process variation.
The four VCOs are packaged in a single, 6 mm × 6 mm,
surface-mount lead frame chip scale package (LFCSP), and
require no external matching components.
Combined with a high frequency, high performance phase-
locked loop (PLL), the ADF41513, the HMC8362 offers a
complete RF or microwave frequency generation solution.
The tuning port is common to all VCO cores for a simpler
design of the phase-locked loop (PLL) feedback path. The
HMC8362 also offers a low typical current consumption of
72 mA for power sensitive applications.

1 Only one VCO band must be powered at a time. VC1 to VC4 are the Band 1 to
Band 4 supply voltages on the VC1 to VC4 pins, respectively.
1 The thermal impedance simulated values are based on the JESD51 standard
using 2S2P on FR4 with four standard JEDEC vias (0.3 mm diameter,
0.025 mm plating, and 1.2 mm pitch).
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the
operational section of this specification is not implied.
Operation beyond the maximum operating conditions for
extended periods may affect product reliability.

HMC8362
THEORY OF OPERATION
The HMC8362 consists of four fundamental VCOs with
overlapping frequency ranges to ensure continuous frequency
coverage from 11.90 GHz to 18.30 GHz over all conditions.
are in parallel and being tuned simultaneously. A single buffer
amplifier is also shared by all four VCOs.
The upper circuitry of the buffer amplifier is biased by VCB
(Pin 8). The lower portion of the buffer amplifier or VCB
remains off and very little current flows until one of the VCO
cores is enabled.
Using four oscillators instead of a single oscillator to span the
frequency range reduces the percent bandwidth and tuning
sensitivity of each oscillator, improving phase noise performance.
Tuning sensitivity flatness across the frequency range is also
improved and simplifies the loop filter design in synthesizer
applications. The tuning sensitivity is similar across the four
VCO cores, which means that the loop bandwidth and phase
margin of the loop filter vary less overall vs. a single oscillator
solution.
The lower circuitry of the buffer amplifier is enabled when the
RF signal of any one of the four VCOs arrives at its input. If
VCB is biased and any VCO core is enabled, current flows
through the buffer amplifier and the RF signal propagates to
RFOUT (Pin 5).
The buffer amplifier is designed to support only one VCO at a
time. Avoid enabling more than one oscillator at a time because
multiple oscillators stress the buffer amplifier enough to reduce
its long-term operating life.
The four oscillators share a common tune port, which means
that even though the active devices in the unused VCO cores
are not being biased, the resonant tanks of all four VCO cores

APPLICATIONS INFORMATION
The HMC8362 serves as the local oscillator (LO) in microwave
synthesizer applications. The primary applications for this
device are point to point and multipoint radios, military radars,
test and measurement, industrial and medical equipment, and
wireless communication infrastructure. The low phase noise
allows higher orders of modulation and offers improved bit
error rates in communication systems. Stable loop filter design
is easily achieved due to the linear, monotonic tuning
sensitivity across the four-VCO core, and higher output power
minimizes the gain required to drive subsequent stages. The
cascode output buffer amplifier stage guarantees stability over a
wide range of output load conditions and improves the pulling
performance of the VCO cores.
multiplexer such as the ADG1604 is recommended. The
ADG1604 has low on resistance, the ability to operate with
either 3 V or 5 V logic, and offers break before make switch
sequencing. Alternatively, multiple ADG854 switches can also
be used to enable and disable the VCO cores. Although this
switch also includes a break before make delay, users must
prevent the possibility of powering up more than one VCO
core at a time. Regardless of which approach is used to control
the VCO cores, an additional ADG854 can be used to control
bias to the upper portion of the cascode amplifier circuitry for
use in muting the RF output (RFOUT, Pin 5) if desired. Muting
RFOUT suppresses the output power by approximately 20 dB
across all cores) and does not impact long-term reliability when
only one VCO core is powered up at a time.
To achieve optimal performance of the VCO cores, including
the lowest phase noise native to VCOs, high power supply
rejection ratio (PSRR) and low dropout (LDO) regulators are
recommended to minimize any spurious frequencies from the
power supply, and to achieve the lowest phase noise native to
the VCO. The ADM7150 and the LT3042 meet these requirements
and are acceptable LDO regulators to use.
It is important to follow optimal RF layout practices for the
layout of the interconnecting circuit. Give first priority to the
microwave power splitter network from the output buffer of
the VCO cores to the RF input pin (RFINA) of the ADF41513.
Give the next highest priority to the highly sensitive VTUNE line
with the first pole placed as close to the ADF41513 CP output
pin as possible, and the final RC pole of the filter placed as close
to the HMC8362 VTUNE pin as possible. The wide tuning range
of the HMC8362 requires the use of a high voltage, low noise,
operational amplifier. The ADA4625-1 is acceptable to use for
such applications.
The wide frequency range of the VCO cores suggests the use of
a low noise, PLL synthesizer, such as the ADF41513. The wide
input bandwidth of the ADF41513 (1 GHz to 26.5 GHz) makes
it an ideal synthesizer to be used with the HMC8362. The charge
pump current can be varied up or down on the ADF41513 to
compensate for VCO sensitivity variation. Many applications
require actively switching between the four VCO cores as
quickly as possible. Enabling more than one VCO core at a time
is not recommended. Therefore, use of an appropriate 4:1
The suggested PCB stackup consists of a high quality dielectric
material, such as Rogers 4003. The transmission lines carrying
the high frequency signal must be carefully controlled with
50 Ω characteristic impedances.
