RFX242

2.4GHz High Power 802.11ac WLAN Linear Power Amplifier

Please note: RFX242 is being discontinued and is not recommended for new designs. The suggested replacement is SE2623L

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 the 2.4GHz frequency range.

The RFX242 provides 30dB gain and up to 25dBm linear output power 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 input impedance matching, as well as integrated RF decoupling for the power supply.

The RFX242 is assembled in a compact 3.0x3.0mm 16L-QFN package.

It requires minimal number of external components to greatly simplify RF front-end implementation.
