General Description
The HMC404 chip is a sub-harmonically pumped (x2) MMIC image rejection mixer with an integrated LO amplif 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 amplif er is a single bias (+4V) two stage design with only +2 dBm nominal drive required.
