Diplexer. In case of 5 GHz sending signal, the signal goes through Notch Filter

and it is amplified in power amplifier. The converted signal is then transmitted to

the antenna after going through 5 GHz LPF, SPDT switch and Diplexer.

Receiving Path

The RF signal received from the antenna is transmitted to 5 GHz or 2.4 GHz

receiving part through Diplexer. In case of 2.4 GHz receiving signal, the signal

goes through LPF, SPDT RF switch and BPF, then it is transmitted to Baseband

chipset after it is amplified in 2.4 GHz LNA part. In case of 5 GHz receiving

signal, the signal goes through SPDT RF switch and Notch Filter, then it is

transmitted Baseband chipset after it is amplified in 5 GHz LNA part.

The data received in Baseband chipset is demodulated and is transmitted to CPU.

It is then transmitted through the Ethernet transceiver and the main processor.
