General Description
The FMPA2151 is a dual frequency band power amplifier
module designed for high performance WLAN applications in
the 2.4-2.5 GHz and the 4.90-5.9 GHz frequency bands. The 16
pin 4 x 4 x 1.4 mm package with internal matching on both input
and output to 50 Ohms minimizes next level PCB space and
allows for simplified integration. Only two external bias bypass
capacitors are required. The two on-chip detectors provide
power sensing capability. The PA’s low power consumption and
excellent linearity are achieved using our InGaP Heterojunction
Bipolar Transistor (HBT) technology.
