ATF61501-11
5 GHz Power Amplifier
The ATF61501-11 is power amplifier (PA) designed for 5.1~5.9GHz frequency range, compatible with 802.11ax/802.11ac wireless LAN system. The device is manufactured based on advanced InGaP/GaAs HBT
(Hetero-junction Bipolar Transistor) process. The amplifier consists of 3 gain stages with inter-stage matching, build-in input matching network, and a power detector for close loop power control operation.
The device is provided in a tiny industry standard 16-lead surface mountpackage QFN 3mmX3mm.
