RoHS COMPLIANT
12.5-17GHz Low-Noise Driver Amplifier
GaAs Monolithic Microwave IC
Description
The CHA2266 is a self biased, low-noise
high gain driver amplifier. It is designed
mainly for VSAT applications in Ku-
band. The backside of the chip is both RF
and DC grounded. This helps to simplify
the assembly process.
The circuit is manufactured on a standard
GaAs pHEMT process, with via holes
through the substrate, air bridges and
electron beam gate lithography.
It is available in chip form.
