RFS P2023 2.4 GHz 802.11b/g www.DataSheet4U.com WLAN Power Amplifier Data Sheet - Rev 2.3 FEATURES <3% EVM, 145 mA @ POUT = +19 dBm with IEEE 802.11g Modulation at 54 Mbps -38 dBc ACPR 1st Sidelobe at +23 dBm with IEEE 802.11b Modulation at 11 Mbps -54 dBc ACPR 2nd Sidelobe at +23 dBm with IEEE 802.11b Modulation at 11 Mbps No RF Matching Required 34 dB of Linear Power Gain Temperature-Compensated Linear Power Detector APPLICATIONS IEEE 802.11 b/g WLAN 2.4 GHz Cordless Phones 2.4 GHz ISM Equipment S28 Package 16 Pin 3 mm x 3 mm x 0.9 mm LPCC PRODUCT DESCRIPTION The RFS P2023 power amplifier is a high performance InGaP HBT IC designed for transmit applications in the 2.4-2.5 GHz band. The part is matched at the input and output so no additional RF matching components are required off-chip. The VCC1 NC PA exhibits unparalleled linearity and efficiency for both 802.11g and 802.11b WLAN systems. The power detector is temperature compensated on chip enabling a single-ended output voltage. The part is biased by a single +3.3 V supply.
