Claim 8:
9. The ROF communication remote machine according to claim 1, wherein the ROF communication remote machine is configured to adapt to an FDD 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;
the power coupler for separating the downlink electrical signal received from the power amplifier into two electrical signals, one of which is sent to an isolator, and the other signal is sent to the first port in the second branch in the form of the downlink electrical signal;
an isolator for receiving the downlink electrical signal sent by the power coupler and sending it to a duplexer; and
wherein the duplexer is for receiving the downlink electrical signal from the isolator and sending it to the antenna, and receiving the uplink electrical signal from the antenna and sending it into the second port in the second branch.
