Abstract
This invention discloses a method and an apparatus for transmitting/receiving signals in a microwave system, and pertains to the field of communications. The transmitting method comprises receiving and modulating a transmission signal transmitted via an optical fiber; processing the modulated transmission signal to generate RF signal; and separating the RF signal to be transmitted from a signal received via an antenna, and transmitting the separated RF signal via the antenna. The receiving method comprises separating a signal received via an antenna from a signal to be transmitted; processing the received signal after being separated to generate IF signal; demodulating the generated IF signal; and transmitting the received signal after being demodulated via an optical fiber. The transmitting/receiving apparatus comprises an optical fiber signal interface, a signal reception module, a modulation module, an IF-RF transmission module, a duplexer, a control module and a power interface. Use of the optical fiber to transmit the transmission signal and the received signal according to the present invention makes it possible for application of large capacity microwave and also greatly saves production cost.
