TriQuint Launches TQM6M4001 Quad-Band GSM GPRS Transmit Module

6/2/2004 - TriQuint Semiconductor, Inc. (Nasdaq/FSE: TQNT) introduced a revolutionary new Quad-Band GSM GPRS Transmit Module (TQM6M4001) in the market's smallest, most highly-integrated form factor – 6x6x1.1mm – offering a 60% size reduction compared to competing solutions with greater system integration and superior cost-effectiveness for next generation mobile handset designs.

The new TQM6M4001 transmit module is a marketplace breakthrough because of its smaller size and high-level integration. This module leverages the discrete GSM850/900 and DCS1800/PCS1900 power amplifier (PA) blocks and integrated power control found in current generation power amplifier modules. It then adds the low insertion loss quad-band pHEMT switch, Tx harmonics filtering, integrated switch decoder, four receive ports, and internal ESD protection necessary to implement full RF transmit/receive functionality - all in an unprecedented size of 36mm2. The TQM6M4001 requires no external matching and saves customers the need for PA-to-switch design effort. This advancement was achieved in part by eliminating all surface mount devices (SMDs) inside the laminate-based module, resulting in clear size, cost, reliability and time-to-market advantages.

“This market-leading GSM GPRS Quad-Band Transmit Module offers outstanding performance and integration while enabling phone designers to significantly simplify and reduce next-generation mobile design form factors. This clear advantage in RF partitioning decreases time-to-market and engineering complexity,” said Andreas Nitschke, TriQuint Semiconductor GSM Product Marketing Manager–Europe.

The TQM6M4001 is a significant milestone in TriQuint’s GSM RF roadmap, which includes a broad technology portfolio of PAMs, switches and filter components. Through innovative engineering the company is committed to set new standards in RF front-end system architecture driving the highest integration while simultaneously offering the best RF performance at the lowest size and cost targets.

The TQM6M4001 utilizes TriQuint’s InGaP, GaAs HBT and GaAs PHEMT processes to combine all transmit functions between transceiver output and antenna:

Key product benefits include excellent RF&DC performance over temperature:

The TQM6M4001 transmit module complements TriQuint`s product family of GSM GPRS power amplifier stand-alone modules (e.g. TQM7M4014 [7x10mm] and TQM7M4022 [7x7mm]) and offers an RF transmit ‘turn-key’ solution by eliminating the need for a separate, front-end switch module, power control circuitry and matching components for the PA and front-end design.

Sample availability for the TQM6M4001 GSM GPRS Quad-Band Transmit Module is limited due to customer demand. Please contact TriQuint for sample updates, demo-boards, application notes and excellent world-wide application team technical support. A product brief for the TQM6M4001 is available at:
