HMC404
GaAs MMIC SUB-HARMONICALLY
PUMPED IRM MIXER, 26 - 33 GHz
Features
Integrated LO Amplifier: +2 dBm Input
Sub-Harmonically Pumped (x2) LO
Image Rejection: 22 dB
Small Size: 1.90 x 1.25mm
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.
