General Description

The RMPA2550 is a dual frequency band power amplifier designed for high performance WLAN applications in the 2.4-2.5 GHz and the 5.15-5.85 GHz frequency bands. The single low profile 20 pin 3 x 4 x 0.9 mm package with internal matching on both input and output to 50? minimizes next level PCB space and allows for simplified integration. The two on-chip detectors provide power sensing capability while the logic control provides power saving shutdown options. The PA’s low power consumption and excellent linearity are achieved using our InGaP Heterojunction Bipolar Transistor (HBT) technology.
