Claim 7:
8. The ROF communication remote machine according to claim 1, wherein the ROF communication remote machine is configured to adapt to a TDD standard, and the second packaging module comprises:
a power amplifier, configured for power-amplifying the downlink electrical signal sent by the first packaging module and sending it to a power coupler;
a power coupler for separating the downlink electrical signal received from the power amplifier into two electrical signals, one of which is sent to a circulator, and the other signal is sent to the first port in the second branch in the form of the downlink electrical signal;
a circulator for receiving the downlink electrical signal from the power coupler and sending it to a filter, and receiving the uplink electrical signal from the filter and sending it to the second port of the second branch; and
a filter for receiving the downlink electrical signal sent by the circulator, filtering the downlink electrical signal and sending it to the antenna, and receiving the uplink electrical signal sent by the antenna, filtering the uplink electrical signal and sending it into the circulator.
