HMC338
GaAs MMIC SUB-HARMONICALLY
PUMPED MIXER, 26 - 33 GHz
Features
Integrated LO Amplifier: -5 dBm Input
Sub-Harmonically Pumped (x2) LO
High 2LO/RF Isolation: 33 dB
Die Size: 1.32 x 0.97 x 0.1 mm
General Description
The HMC338 chip is a general purpose sub-harmoni-
cally pumped (x2) MMIC mixer with an integrated LO
amplifier which can be used as an upconverter or
downconverter in the 26 to 33 GHz frequency range.
The chip utilizes a GaAs PHEMT technology that
results in a small overall chip area of 1.28mm2. The
2LO to RF isolation is excellent eliminating the need
for additional filtering. The LO amplifier is a single
bias (+3V to +4V) two stage design with only -5 dBm
nominal drive requirement. All data is measured with
the chip in a 50 ohm test fixture connected via 0.076
mm (3 mil) ribbon bonds of minimal length <0.31 mm
(<12 mils).
