RoHS COMPLIANT
37-40GHz Integrated Down Converter
GaAs Monolithic Microwave IC
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,
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.
It is available in chip form.
