RMPA5252
4.9–5.9 GHz InGaP HBT WLAN Linear Power Amplifier
Features
■ Full 4.9 to 5.9GHz operation
■ 34dB small signal gain
■ 3% EVM at 18dBm modulated power out
■ 3.3V single positive supply operation
■ Integrated power detector with 20dB dynamic range
■ Lead-free RoHS compliant 3 x 3 x 0.9 mm leadless package
■ Internally matched to 50 Ohms and DC blocked RF input/
output
■ Optimized for use in 802.11a applications
General Description
The RMPA5252 power amplifier is designed for high
performance WLAN applications in the 4.9–5.9 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. An on-chip
detector provides power sensing capability. The PA’s low power
consumption and excellent linearity are achieved using our
InGaP Heterojunction Bipolar Transistor (HBT) technology.
