HMC265
GaAs MMIC SUB-HARMONICALLY
PUMPED DOWNCONVERTER, 20 - 32 GHz
Features
Integrated LO Amplifi er: -4 dBm Input
Sub-Harmonically Pumped (x2) LO
Integrated IF Amplifi er: 3 dB Gain
Small Size: 1.32mm x 1.32mm
General Description
The HMC265 chip is a sub-harmonically pumped
(x2) MMIC downconverter with integrated LO & IF
amplifi ers. The chip utilizes a GaAs PHEMT technology that results in a small overall chip area of
1.74 mm2. The 2LO to RF isolation is excellent
eliminating the need for additional fi ltering. The
LO amplifi er is a single bias (+3V to +4V) two
stage design with only -4 dBm nominal drive
requirement. All data is with the chip in a 50
ohm test fi xture connected via 0.025 mm (1 mil)
diameter wire bonds of minimal length <0.31 mm
(<12 mils). This downconv erter IC is an excellent,
smaller, and more reliable replacement to hybrid
diode based downconverter MMIC assemblies.
