CHE1270a
RoHS COMPLIANT
12-40GHz Wide Band Detector
GaAs Monolithic Microwave IC
Description
The CHE1270a is a detector that integrates a
matched detection diode (Vdet). A reference
diode is also available to be used in
differential mode (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 chip form.
