400MHz to 2.5GHz Upconverter Mixers
General Description
Features
The MAX2660/MAX2661/MAX2663/MAX2671/MAX2673
miniature, low-cost, low-noise upconverter mixers are
designed for low-voltage operation and are ideal for
use in portable consumer equipment. Signals at the IF
input port are mixed with signals at the local oscillator
(LO) port using a double-balanced mixer. These
upconverter mixers operate with IF input frequencies
between 40MHz and 500MHz, and upconvert to output
frequencies as high as 2.5GHz.
ꢀ RF Output Frequencies: 400MHz to 2.5GHz
ꢀ Low Noise Figure: 9.3dB (900MHz, MAX2671)
ꢀ +2.7V to +5.5V Single Supply
ꢀ High Output Intercept Point (OIP3)
5.9dBm at 4.8mA (MAX2660)
7.1dBm at 8.3mA (MAX2661)
0.7dBm at 3.0mA (MAX2663)
9.6dBm at 11.8mA (MAX2671)
7.6dBm at 20.5mA (MAX2673)
These devices offer a wide range of supply currents and
output intercept levels to optimize system performance.
Supply current is essentially constant over the specified
supply voltage range. Additionally, when the devices are
ꢀ 1µA Shutdown Mode
ꢀ Ultra-Small Surface-Mount Packaging
in a typical configuration with V
= 0, a shutdown
SHDN
mode reduces the supply current to less than 1µA.
Pin Configurations
The MAX2660/MAX2661/MAX2663/MAX2671 are
offered in the space-saving 6-pin SOT23 package. For
applications requiring balanced IF ports, choose the
MAX2673 in the 8-pin µMAX package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

_______________Detailed Description
The MAX2660/MAX2661/MAX2663/MAX2671/MAX2673
are 2.5GHz double-balanced upconverter mixers
designed to provide optimum linearity performance for
a specified supply current. These upconverter mixers
use single-ended RF, LO, and IF port connections,
except for the MAX2673, which uses a differential IF
port. An on-chip bias cell provides a low-power shut-
down feature. See the Selector Guide for device fea-
tures and comparison.
CC
capacitor in parallel with an RF capacitor (Table 2). Use
separate vias to the ground plane for each of the
bypass capacitors and minimize trace length to reduce
inductance. Use separate vias to the ground plane for
each ground pin. Use low-inductance ground connec-
tions.
Decouple SHDN with a 100pF capacitor to ground to
minimize noise on the internal bias cell. Use a series
resistor (typically 100Ω) to reduce coupling of high-fre-
quency signals into the SHDN pin.
__________Applications Information
Local-Oscillator (LO) Input
The LO input is a single-ended broadband port with a
return loss of better than 8dB from 600MHz to 2.5GHz.
The LO signal is mixed with the input IF signal, and the
resulting upconverted output appears on the RFOUT
pin. AC-couple the LO pin with a capacitor having less
than 3Ω reactance at the LO frequency. The
MAX2671/MAX2673 include an internal LO buffer and
require an LO signal ranging from -10dBm to +5dBm,
while the MAX2660/MAX2661/MAX2663 require an LO
signal ranging from -5dBm to +2dBm.
______________________Layout Issues
A well-designed PC board is an essential part of an RF
circuit. For best performance, pay attention to power-
supply issues as well as to the layout of the RFOUT
matching network.
Power-Supply Layout
To minimize coupling between different sections of the
IC, the ideal power-supply layout is a star configuration
with a large decoupling capacitor at a central V
CC
node. The V
traces branch out from this central
CC
IF Input
The MAX2660/MAX2661/MAX2663/MAX2671 have a
single-ended IF input port, while the MAX2673 has a
differential IF input port for high-performance interface-
to-differential IF filters. AC-couple the IF pin(s) with a
capacitor. The typical IF input frequency range is
40MHz to 500MHz. For further information, see the IF
Port Impedance vs. IF Frequency graph in the Typical
Operating Characteristics.
node, each going to a separate V
node in the PC
CC
board. At the end of each trace is a bypass capacitor
that has low ESR at the RF frequency of operation. This
arrangement provides local decoupling at each V
CC
pin. At high frequencies, any signal leaking out of one
supply pin sees a relatively high impedance (formed by
the V
trace inductance) to the central V
node, and
CC
CC
an even higher impedance to any other supply pin, as
well as a low impedance to ground through the bypass
capacitor.
RF Output
The RF output frequency range extends from 400MHz
to 2.5GHz. RFOUT is a high-impedance, open-collector
Impedance-Matching Network Layout
The RFOUT matching network is very sensitive to lay-
out-related parasitics. To minimize parasitic induc-
tance, keep all traces short and place components as
close as possible to the chip. To minimize parasitic
capacitance, use cutouts in the ground plane (and any
other plane) below the matching network components.
output that requires an external inductor to V
for
CC
proper biasing. For optimum performance, implement
an impedance-matching network. The configuration
and values for the matching network depend on the fre-
quency, performance, and desired output impedance.
For assistance in choosing components for optimal per-
formance, see Table 1 as well as the RF Output
Impedance vs. RF Frequency graph in the Typical
Operating Characteristics.
