Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, announces the release of a 40W GaAs MMIC Positive Control T/R Switch for Cellular/3G, TD-SCDMA, Private Mobile Radio and Automotive Telematics applications from 0.1 to 2.1 GHz. The HMC646LP2E is a low loss, high linearity GaAs MMIC 40W Switch that provides exceptionally high P0.1 dB compression of +46 dBm (@10% duty cycle) as well as an Input IP3 of +74 dBm on the Transmit (Tx) port, making it ideal for use in transmit-receive or LNA protection applications. Its superior low distortion at high input power levels as well as its fast switching characteristics makes it an ideal choice for the demands of modern basestation infrastructure. On-chip circuitry enables the HMC646LP2E to operate with single positive control voltages from 0/+3V to 0/+8V, with very low DC current consumption. The HMC646LP2E is conveniently housed in a small RoHS compliant 2x2mm DFN surface mount package. Samples are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
