CHE1270-QAG
RoHS COMPLIANT
12-40GHz Wide Band Detector
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHE1270-QAG is a detector that
integrates a matched detector diode (Vdet)
and a reference diode (Vref).
It is designed for a wide range of applications
where an accurate transmitted power control
is required, typically commercial
communication systems.
The circuit is manufactured with a Schottky
diode MMIC process, 1µm gate length, via
holes through the substrate and air bridges.
It is available in leadless SMD package.
