CHA3511
RoHS COMPLIANT
6-18GHz Amplifier
GaAs Monolithic Microwave IC
Description
The CHA3511 is composed of a Single Pole
Single Through (SPST) switch followed by a
double stage travelling wave amplifier. It is
designed for defence, naval, or avionic
applications. 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-
HEMT process, 0.25µm gate length, via
holes through the substrate, air bridges and
electron beam gate lithography.
It is available in chip form.
