Description
The CHE1270a99F is a detector that
integrates a matched detection diode (Vdet).RF IN
A reference diode is also available to be
Matching
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
Vdet
Vref
holes through the substrate and air bridges.It is available in chip f
