CHE1270-QAG/21 United Monolithic Semiconductors

CHE1270-QAG RoHS COMPLIANT 5-44GHz 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). UMS It is designed for a wide range of applications E1270 where an accurate transmitted power control YYWW is required, typically commercial communication systems. The circuit is manufactured with a Schottky diode MMIC process, 1m gate length, via holes through the substrate and air bridges. CCHHEE11227700 RRFF IINN It is supplied in RoHS compliant SMD MMaattcchhiinngg package.
