Integrated LO Amplifier: -5 dBm Input
Sub-Harmonically Pumped (x2) LO
High 2LO/RF Isolation: 33 dB
Small Size: 0.97mm x 1.32mm
General Description
The HMC338 chip is a sub-harmonically pumped
(x2) MMIC mixer with an integrated LO amplifier
which can be used as an upconverter or downcon-
verter. 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 mea-
sured with the chip in a 50 ohm test fixture con-
nected via 0.076 mm (3 mil) ribbon bonds of minimal
length <0.31 mm (<12 mils).
