CHR3693-99F
21-26.5GHz Integrated Down converter
GaAs Monolithic Microwave IC
Description
The CHR3693-99F is a multifunction chip,
which integrates a balanced cold FET mixer,
I
a time two multiplier, and a RF self biased
LNA.
It is designed for a wide range of applications, typically commercial communication systems.
Q
The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes
through the substrate, air bridges and electron
beam gate lithography.
It is available in chip form.
