CHR3693 Datasheet, PDF (1/6 Pages) United Monolithic Semiconductors – 21-26.5GHz Integrated Down converter

CHR3693
21-26.5GHz Integrated Down converter
GaAs Monolithic Microwave IC
Description
The CHR3693 is a multifunction chip, which
integrates a balanced cold FET mixer, a time
two multiplier, and a RF self biased LNA. It is
designed for a wide range of applications,
typically commercial communication systems.
The backside of the chip is both RF and DC
grounded. This helps to simplify the assembly
process.
The circuit is manufactured with a PM-HEMT
process, 0.25µm gate length, via holes
through the substrate and air bridges.
It is supplied in chip form.
