Claim 0:
1. An access network device, wherein the access network device comprises a signal processing apparatus, wherein the signal processing apparatus comprises a power amplification module, a processing module connected to the power amplification module, and a communication module connected to the processing module, and wherein:
the power amplification module comprises a first power amplifier and a second power amplifier;
the processing module comprises:
a first filter connected to the first power amplifier;
a second filter connected to the second power amplifier; and
a combiner connected to the first filter, the second filter, and the communication module;

the first power amplifier is configured to:
perform power amplification on a received first signal to obtain a second signal; and
send the second signal to the first filter;

the first filter is configured to:
receive the second signal sent by the first power amplifier; and
filter the second signal to obtain a first sub-signal and a second sub-signal, wherein the first sub-signal belongs to a first frequency band, and the second sub-signal belongs to a second frequency band;

the second power amplifier is configured to:
perform power amplification on a received third signal to obtain a fourth signal; and
send the fourth signal to the second filter;

the second filter is configured to:
receive the fourth signal sent by the second power amplifier; and
filter the fourth signal to obtain a third sub-signal, the third sub-signal belongs to a third frequency band;

the combiner is configured to:
combine the first sub-signal and the third sub-signal to obtain a first combined signal; and
send the first combined signal and the second sub-signal to the communication module; and

the communication module is configured to:
send the first combined signal by using a first port; and
send the second sub-signal by using a second port.
