General Description
The HMC404 chip is a sub-harmonically pumped
(x2) MMIC image rejection 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
2.31mm2. The on-chip 90° hybrid provides excellent
amplitude and phase balance resulting in greater than
22 dB of image rejection. The LO amplifier is a single
bias (+4V) two stage design with only +2 dBm nominal
drive required.
Electrical Specifications, TA = +25° C
IF = 1 GHz
LO = +2 dBm & Vdd = +4V
