Analog Devices Intros GSM/GPRS Power Amplifier

Analog Devices Inc. (ADI, Wilmington, MA) announced it has entered the cellular handset power amplifier market with the introduction of its new X-PA™ family of RF power amplifier modules. The new PA modules integrate the company's RF detection and power control technology enabling cell phone manufacturers to achieve longer battery life, improve performance and lower manufacturing costs.

The first product in the new X-PA™ family of power amplifier modules is the ADL5551, which is the cellular industry's first power amplifier module with integrated control using closed-loop, output power measurement. The new module employs gallium arsenide, hetero-junction bipolar, power amplifier process technology, which results in battery power savings of more than 20 percent.

The ADL5551 complements ADI's Othello® GSM RFIC product family and is quad-band GSM- (850MHz, 900MHz, 1,800MHz and 1,900MHz) and GPRS-compliant to level 12. The device operates with a 2.9V to 4.5V power supply and is available in a 10mm x 10mm x 1.4mm LCC package. Pricing for the ADL5551 starts at $5 per unit in 10,000-piece quantities. The device is in full production now.
