AP1091

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. • 26/24 dBm Linear Output Power at 5/3.3 V • Power Supply With 11Mb/s, CCK Modulation • 19 dBm Linear Output Power With 54Mb/s, OFDM Modulation (about 3% EVM) • 28 dB Small Signal Gain • Single 3.3 V Power Supply • On-Chip Power Detector Major Applications • IEEE802.11b WLAN System • IEEE802.11g (draft) WLAN System • 2.4GHz ISM Radios Pin Details Pin Number 1 2 3 4 Name RF_IN GND Dect_V Dect_Out VB1 VB2 GND NC NC RF_OUT RF_OUT RF_OUT VCC1 VCC1 NC NC Description RF input.
