Description
The RMPA5255 power amplifier module is designed for high
performance WLAN applications in the 4.9–5.9 GHz frequency
band. The 10 pin, 5 x 5 x 1.5 mm package with internal match-
ing on both input and output to 50 Ω , and internal bias network
components, allow for extremely simplified integration. An on-
chip detector provides power sensing capability. The PA’s low
power consumption and excellent linearity are achieved using
our InGaP Heterojunction Bipolar Transistor (HBT) technology.
