RMPA5251 Datasheet 4.90-5.85 GHz InGaP HBT Linear Power Amplifier

Manufacturer: Fairchild (now onsemi)

General Description

The RMPA5251 power amplifier is designed for high performance WLAN applications in the 4.9 to 5.35 and 5.15 to 5.85 GHz frequency bands.

The low profile 16 pin 3 x 3 x 0.9 mm package with internal matching on both input and output to 50Ω 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.
