Functional Diagram
General Description
The HMC404 chip is a sub-harmonically pumped
(x2) MMIC image rejection mixer with an integrated
LO ampli鏗乪r 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
2.31mm
2
. The on-chip 90擄 hybrid provides excellent
amplitude and phase balance resulting in greater
than 22 dB of image rejection. The LO ampli鏗乪r is a
single bias (+4V) two stage design with only +2 dBm
nominal drive required.
