AP1091 is a linear, two stages power amplifier MMIC

with high output power in 2.4GHz band utilizing

InGaP/GaAs HBT process. With the excellent linearity

performance, the device delivers 26 dBm of linear

output power (at 5V power supply)compliant with the

IEEE802.11b standard, and 19 dBm output power,

under 54Mbps OFDM (IEEE802.11g) modulation, with

only 3% EVM. The PA also includes on-chip power

detector, providing a DC voltage proportional to the

output power of the device. It features a small signal

gain of 28 dB and P1dB of 26.5 dBm at 3.3V power

supply. AP1091 is housed in a 3 x 3 (mm),16 Pin QFN

leadless package.
