Cree Microwave Inc. has announced the release of the CRF-22010 SiC MESFET power transistor that is designed to cover the entire DCS/PCS/UMTS frequency band of 1.8GHz to 2.2GHz.

The 48V, 10W, Class A transistor delivers a 12dB gain at 2.2GHz. In a demonstration, the company produced a balanced amplifier using two CRF-22010 MESFETs that delivered 22W across a 400MHz bandwidth.

"We believe this outstanding wide bandwidth demonstration highlights the future impact of wide bandgap semiconductors for the cellular infrastructure market. One amplifier design can serve multiple frequency bands and multiple air-interface protocols (W-CDMA, CDMA, GSM, EDGE)," said John Palmour, Director of Advanced Devices at Cree Inc.
