RFX240 Production Data Sheet 2.4GHz High Power 802.11n WLAN Linear Power Amplifier DESCRIPTION The RFX240 is high power, high linearity power amplifier NC VDD1 NC NC implemented in CMOS process. The device is optimized to provide all functionality of transmit power amplification for IEEE RFIN GND 802.11b/g/n applications in the 2.4GHz frequency range. The RFX240 provides 30dB gain and up to +26dBm linear output power with low EVM of <3% for 802.11n MCS7 HT40 signals. It RFOUT PAEN has CMOS logic control, on-chip input impedance matching, as well as integrated RF decoupling for the power supply. The RFX240 is assembled in a compact 3.0x3.0mm 16L-QFN GND RFOUT package. It requires minimal external components to greatly Bias simplify RF front-end implementation.
