Abstract： This paper introduces a WiFi digital RF front-end architecture which can be used for ASIC. It is compatible with 802.11b/a/g/n/ac/ax protocol in 2.4 GHz and 5 GHz channels. Combined with analog receiving circuit, ADC and demodulator, the functions of signal type differentiation, power locking of different types of signals, filtering and resampling of signals with different bandwidth are realized.
