Features
INTEGRATED LO AMPLIFIER: -4dBm INPUT
SUB-HARMONICALLY PUMPED (x2) LO
HIGH 2LO/RF ISOLATION: > 35dB
SMALL SIZE: 0.97mm x 1.32mm
General Description
The HMC264 chip is a sub-harmonically pumped
(x2) MMIC mixer with an integrated LO amplifier
which can be used as an upconverter or
downconverter. The chip utilizes a GaAs PHEMT
technology that results in a small overall chip
area of 1.28mm
excellent eliminating the need for additional filtering. The LO amplifier is a single bias (+3V to
+4V) two stage design with only -4dBm nominal
drive requirement. This mixer chip is designed to
be used in local multi-point distribution (LMDS)
systems, microwave point-to-point radios, and
SATCOM applications. All data is measured with
the chip in a 50 ohm test fixture connected via
0.025 mm (1 mil) diameter wire bonds of minimal
length <0.31 mm (<12 mils).
