CHR3394-QEG Datasheet Down Converter

Manufacturer: United Monolithic Semiconductors

Overview: CHR3394-QEG 37-40GHz Down Converter GaAs Monolithic Microwave IC in SMD leadless.

General Description

The CHR3394-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.

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.
