TriQuint Semiconductor Inc. unveiled what it claims as the world's smallest high power antenna switch for CDMA applications.

Housed in a 2-by-2-by-0.57mm, 12-lead STSLP package, the TQP4M3019 antenna switch, which is in single-pole triple-throw (SP3T) configuration, promises to provide excellent cross-modulation and isolation performance while exhibiting low insertion loss in all frequency bands (PCS, cellular and GPS).

This new product is designed to provide a low current replacement for classic PIN diode-based switches, and is intended for applications in which the antenna of a CDMA cellphone is routed to the cellular duplexer, the PCS duplexer and the GPS receiver input. The design is symmetric and broadband, which allows the user to assign cellular, PCS and GPS to the three RF ports.

Some key specifications include: cellular and GPS insertion loss of 0.5dB; PCS insertion loss of 0.6dB; cellular isolation of 27dB; GPS isolation of 24dB; PCS isolation of 22dB and an ESD rating of 300V for HBM and 2,000V for CDM.

Samples and production quantities of the TQP4M3019 SP3T CDMA cellphone switch are already available.
