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.
