Description

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, AP1091 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 mgain 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.
