This paper describes a Quad Flat Non-lead (QFN 2x2) packaged PIN diode switch that is capable of handling Continuous Wave (CW) power up to 40W and WCDMA signal up to 10W. The target application is the Transmit arm of a Transmit Receive switch for cellular base-stations. The part was developed in response to this market segment's aggressive cost-cutting pressure. Prior designs relied on more expensive ceramic packages.
