CHA3694 Datasheet, PDF (1/12 Pages) United Monolithic Semiconductors – 31-40GHz Variable Gain Amplifier

CHA3694
RoHS COMPLIANT
31-40GHz Variable Gain Amplifier
GaAs Monolithic Microwave IC
Description
The CHA3694 is a variable gain broadband
Vd
three-stage monolithic amplifier. It is designed
for a wide range of applications, typically
commercial communication systems.
RFin
The backside of the chip is both RF and DC
…
grounded. This helps to simplify the assembly
process.
The circuit is manufactured with a power
pHEMT process, 0.15µm gate length, via
Vctrl
Vg
holes through the substrate and air bridges.
It is supplied in chip form.
