DC to 12GHz, CASCADABLE pHEMT MMIC
Package: QFN, 16-Pin, 3mmx3mm
RFMD’s SUF-8533 is a monolithically matched high IP3 broadband pHEMT
MMIC amplifier covering DC to 12GHz. This pHEMT FET based amplifier
uses a self-bias Darlington topology featuring a gain and temperature
compensating active bias network that operates from a single 5V supply.
It offers efficiency, cascadable performance in a compact 3mmx3mm
Ceramic QFN package. It is well suited for RF, LO, and IF driver applica-
