21- 27.5GHz Power Amplifier
GaAs Monolithic Microwave IC in SMD leadless package
Description
36 lead 6x5 mm QFN package
The CHA6652-QXG is a three stage
monolithic GaAs high power circuit producing
2 Watt output power. It is highly linear, with
possible gain control and integrates a power
detector. ESD protections are included.
It is designed for Point To Point Radio.
The circuit is manufactured with a pHEMT
process, 0.15µm gate length.
It is supplied in RoHS compliant SMD
package.
