DESCRIPTION
The RFX240 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 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 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 package. It requires minimal external components to greatly simplify RF front-end implementation.
