General Description

The RMPA2458 power amplifier is designed for high performance WLAN applications in the 2.4–2.5 GHz frequency band. The low profile 16 pin 3 x 3 x 0.9 mm package with internal matching on both input and output to 50 Ohms minimizes next level PCB space and allows for simplified integration. The on chip detector provides power sensing capability while the bias control provides power saving shutdown capability. The PA’s industry leading low power consumption and excellent linearity are achieved using our InGaP Heterojunction Bipolar Transistor (HBT) technology.
