DESCRIPTION
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.
