General Description

The CHR3894-QEG is a multifunction monolithic receiver, which integrates a balanced cold FET mixer, a LO chain with buffers associated to a time two multiplier, and a RF low noise amplifier including gain control.

It is designed for a wide range of applications, from military to commercial communication systems.

The circuit is manufactured with a pHEMT process, 0.15µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.
