Preliminary RFSP2020 2.4–2.5 GHz Power Amplifier Product Description Applications The RFSP2020 power amplifier is a highperformance GaAs HBT IC designed for use in transmit applications in the 2.4-2.5 GHz frequency band. With a P1dB of 25 dBm, the device is ideal as a final stage for wireless LAN applications requiring high transmit linearity. Designed with advanced linearizing techniques, the device achieves a specific error vector magnitude (EVM) with lesser backoff than conventional PA designs. The PA exhibits unparalleled linearity and efficiency for both 802.11b- and 802.11g-based WLAN systems. The on-chip detector is perfect for systems where power sensing is necessary. The part operates off a single +3.3V supply. 802.11b/g WLAN 2.4 GHz ISM band wireless equipment • • VPC1 3 VCC3 2 VCC2 GND GND 1 VCC1 RF IN 16 15 14 13 Input Match Output Match Bias Bias 12 GND 11 RF OUT 10 GND Product Features Detector VPC2/3 4 9 • NC • 5 6 7 8 • VBC1 VBC2/3 DET REF DET OUT • • Functional Block Diagram • • 25 dBm [email protected] 30 dB gain 1.5 % EVM @ POUT = +18 dBm with 54 Mbps OFDM signal 110 mA @ POUT = +18 dBm with 54 Mbps OFDM signal Single +3.3V supply voltage PA power on/off logic Input and output matched to 50 ohms 1.00 0.80 4 3.00 0.275 0.225 Pin 1 16 Index Area 0.45 0.35 1 3.00 0.50 TYP 1.
