RMPA5251
4.90–5.85 GHz InGaP HBT Linear Power Amplifier
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 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.
