Integrated LO Amplifi er: +2 dBm Input
Sub-Harmonically Pumped (x2) LO
Image Rejection: 22 dB Typical
Small Size: 1.24mm x 1.86mm
General Description
The HMC404 chip is a sub-harmonically pumped
(x2) MMIC image rejection mixer with an integrated LO amplifi er 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 amplifi er is a single bias (+3V to
+4V) two stage design with only +2 dBm nominal
drive required.
