Korean Handset Manufacturers Select Triquint TQP4M3007 pHEMT Switches

5/26/2004 - TriQuint Semiconductor, Inc. (Nasdaq: TQNT) announced initial purchase orders from two major Korean handset manufacturers for its TQP4M3007 pHEMT single-pole, three-throw (SP3T) packaged switch for CDMA wireless phones. TriQuint’s switch contains a single, monolithic die and reduces component count in next-generation handsets by replacing two components: a single-pole, double-throw (SPDT) switch and a diplexer. The TriQuint solution thereby cuts costs and frees board space while enabling a single antenna to service cellular, PCS and GPS bands.

“We are excited about the successful entry of our CDMA switch into full production and the strong interest it’s generating from key customers. The recent Korean purchase orders are the first return on our investment in CDMA switch technology,” said Bruce Fournier, Vice President, TriQuint Semiconductor. “The product’s excellent cross-modulation performance, its reliability, ruggedness and its reduction in component count were decisive factors in these sales.”

TriQuint’s SP3T switch is a single die in a plastic package ideally suited to routing the antenna in CDMA handsets to the cellular duplexer, PCS duplexer and GPS receiver input. The TQP4M3007 has a form factor of just 3x3x0.9mm, replacing multiple components in existing handsets. The TQP4M3007 offers optimum cross-modulation performance under CDMA full duplex operation, which enables superior single tone desense performance compared to competing products. The new switch also offers excellent electro static discharge (ESD) protection. It has survived contact discharge tests, without failure, up to 18kV in CDMA handsets when used in conjunction with a single external ESD protection inductor.

TriQuint’s new SP3T switch completes the company’s initiative to offer both standard approaches favored by the industry for routing a CDMA antenna to PCS, cellular and GPS bands. The TQP4M3007 and TriQuint’s passive triplexer module, 890039 (with built-in GPS filter), feature low-loss performance and offer designers discrete or integrated solution options.

“The availability of our SP3T switch provides manufacturers a choice in defining their CDMA front-end architecture. TriQuint’s broad technology portfolio strategy is being validated in the marketplace,” Fournier added.
