Quad-Band Amplifier

Wed, 07/30/2003 - 9:51am

Analog Devices announces a next-generation quad-band X-PA power amplifier module for GSM/GPRS cell phones. The ADL5552 X-PA power amplifier module features an integrated control loop architecture and single-point calibration. For improved signal integrity under all conditions, the ADL5552 uses directional coupling within its power control loop. The performance of the ADL5552 is beneficial in varying VSWR environments in which cell phones typically operate. In addition, the power amplifier measures 8 × 6 × 1.4 mm. The X-PA architecture uses logarithmic detection to provide precise exponential (linear-in-dB) output power control over a range of 40 dB. The device is based on Gallium Arsenide (GaAs) hetero-junction bipolar (HBT) power amplifier process technology.
