RFX242 Advanced Data Sheet 2.4GHz High Power 802.11ac WLAN Linear Power Amplifier DESCRIPTION NC VDD1 NC NC The RFX242 is high power, high linearity power amplifier implemented in CMOS process. The device is optimized to provide all functionality of transmit power amplification for IEEE 802.11b/g/n/ac applications in RFIN NC the 2.4GHz frequency range. PAEN The RFX242 provides 30dB gain and up to 25dBm linear output power RFOUT with low EVM of <3% for 802.11n MCS7 HT40 and <1.8%g for 802.11ac MCS9 VHT20 signals. It has CMOS logic control, on-chip GND RFOUT input impedance matching, as well as integrated RF decoupling for the Bias power supply. Network VDD0 NC The RFX242 is assembled in a compact 3.0x3.0mm 16L-QFN package. NC NC DET NC It requires minimal number of external components to greatly simplify RF front-end implementation.
