General Description
The RMPA2455 power amplifier is designed for high
performance WLAN access point 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
minimizes next level PCB space and allows for simplified
integration. The on-chip detector provides 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.
