Apparatus and methods for wireless local area network (WLAN) power amplifiers are
provided. In certain configurations, a WLAN power amplifier system includes a WLAN power
amplifier, an output impedance matching network, and an envelope tracker. The WLAN
power amplifier includes an input that receives a WLAN signal having a fundamental
frequency and an output that generates an amplified WLAN signal for transmission over an
antenna. The output impedance matching network is electrically connected to the output of …
