Anadigics claims that its AWT6201 PowerPlexer, in a 10.5-by-11mm module, is the smallest quad-band RF transmit module available for use in GSM/GPRS and GPRS/UMTS cellular phone handsets.

Combining such technologies as InGaP HJBT power amplifiers, pHEMT antenna switches, integrated passives filters, and integrated CMOS power control circuitry, the AWT6201 simplifies the development of single-mode GPRS or dual-mode GPRS/UMTS handsets, the company said.

"Anadigics is addressing the growing demand for integrated transmit module solutions for the 2.5G GPRS and the emerging 3G market," said Ali Khatibzadeh, VP of wireless products at Anadigics.

The module supports GPRS Class 12 in the GSM850/900/DCS/PCS bands. It operates from a single 3.5V supply and has an integrated power controller that is said to simplify the radio design and ensure high manufacturing yield with minimal power control calibration requirements.

Harmonic filtering is achieved with integrated passive technology that enables low signal loss and guarantees conducted spurious performance up to 12.75GHz. Further, Anadigics' pHEMT technology enables embedded RF switches to deliver excellent isolation and linearity while supporting four receive ports. High-gain InGaP HBT power amplifiers ensure compatibility with available GPRS chipsets.

In quantities of 10,000 units, the AWT6201 is priced at $4.50.
