General Description

The CHR3894-98F is a multifunction monolithic receiver, which integrates a balanced cold fet mixer, a LO chain with buffers associated to a time two multiplier, IF_I and a RF low noise amplifier including gain control.

It is designed for a wide range of IF_Q 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.
