Analog Devices Inc. (ADI, Wilmington, MA) announced its next-generation quad-band X-PA™ power amplifier module for GSM/GPRS cell phones. The new ADL5552 X-PA power amplifier module features an integrated control loop architecture and single-point calibration, both of which ease the design process and minimize manufacturing costs. In addition, the power amplifier is provided in a small 8mm x 6mm x 1.4mm package.
The ADL5552 is a high output-power, high-efficiency, mobile handset, power amplifier module with integrated RF power control and measurement. The ADL5552 is ADI's second product in its X-PA family of power amplifier modules providing precise power control over a wide dynamic range. The X-PA architecture uses logarithmic detection to provide precise exponential (linear-in-dB) output power control over a range of 40dB. The device is based on Gallium Arsenide, hetero-junction, bipolar, power amplifier, process technology.
The ADL5552 is quad-band GSM (E-GSM, GSM-850, DCS and PCS) and GPRS-compliant to level 12. It operates with a 2.9V to 4.5V power supply and is available in a 8mm x 6mm x 1.4mm LCC package. Pricing for the ADL5552 starts at $3 per unit in 10,000-piece quantities. The device is sampling now and will be in full production in August 2003.
