AP1091
2.4~2.5 GHz Power Amplifier
2003.03.27
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.
