The invention discloses an optical radio frequency analog transmission signal transceiver which includes a continuous wave laser, an optical intensity modulator, a modulation signal amplifier and an optical path switch connected in sequence through an optical fiber. The continuous wave laser is connected with a drive circuit, an APC circuit and an ATC circuit. The optical intensity modulator is connected with a radio frequency circuit through a radio frequency cable. The optical intensity modulator is connected with an automatic bias controller. The optical path switch is connected with a control circuit and a PD optical circuit. The PD optical circuit is connected with a radio frequency AGC amplifier circuit. The radio frequency AGC amplifier circuit is connected with a radio frequency amplitude limiter circuit. The radio frequency amplitude limiter circuit is connected with a radio frequency output circuit. The problem of large-capacity signal transmission can be solved. The anti-interference ability and the capacity and quality of communication signals are obviously improved. In addition, physical construction is greatly reduced, environmental protection is greatly improved, andthe radiation of spatial radio frequency signals is reduced.
