RMPA2550 - Fairchild Semiconductor

RMPA2550 2.4-2.5 GHz and 5.15-5.85 GHz Dual Band InGaP HBT Linear Power Amplifier

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 Ω minimizes next level PCB space and allows for simplified integration. The two on-chip detec.
