TriQuint Semiconductor Inc. announced the addition of two new GSM-EDGE switch products to complement its existing CDMA handset switch product line. According to the company, they are expanding its advanced switching product line to support the needs of handset designers.

The TQD4M4014 phemt single-pole, six-throw (SP6T) switch is a bare die that includes a built-in 3-line Logic Decoder. Using the strengths of TriQuint's E-D PHEMT wafer fabrication process, this switch is a single monolithic die that reduces the control lines from 7 to just 3 with an on-chip integrated logic decoder, said the press release. The integrated logic decoder requires 110mA of DC current at 2.7V under full 35dBm GSM Tx power conditions. Additionally, the single die replaces two die components: a single-pole, SP6T switch and a separate CMOS logic decoder.

Meanwhile, the second recently announced deviceTQP4M4010, is a single-pole, four throw (SP4T) version, targeted at dual-band applications and offered in a low profile SLIM-17 package (2.5-by-2.5-by-0.6mm).

According to TriQuint, low insertion loss, robust harmonic performance under mismatch and ESD rated at 250V HBM are the key features of its two new products. "The product's excellent harmonic performance, lowest in-class power consumption and reduction in component count are decisive factors that will accelerate the adoption of pHEMT technology as replacement for PIN diodes," commented Paul Cooper, Switch Product Marketing Manager at TriQuint. "The availability of our SP6T and SP4T GSM-EDGE switches provides manufacturers a clear path to miniaturization of front-end architectures."
