Design power amplifier using load pull method in WLAN 802.11 ax access point application

WLAN is a widely used standard telecommunication protocol. Currently IEEE802.11ac standard has some limitations along with the increasing need for fast communication and able to serve many devices. The development of the IEEE 802.11ax standard is expected to overcome these limitations. Some challenges on the design of power amplifiers also appear as the development of 802.11ax standard. Power amplifiers on the access point are expected to provide a minimum output of 30dBm. This paper explains the design and modeling of power amplifiers on access point using load pull method. Based on the design and test result using CGH27030 transistor with simulation approach harmonic balance obtained that the output power of half wave obtained optimum value 33,023 dBm at input value 19 dBm and EVM equal to 4,8%.
