The present disclosure discloses a multi-standard performance reconfigurable I/Q orthogonal carrier generator. The generator may implement a continuously covered I/Q carrier output of 0.1-5 GHz and continuously covered differential signal outputs of 5-10 GHz and 1.5-3 GHz by means of reasonable frequency assignment; also, carrier signals under various frequencies with different loop bandwidths, different phase noises, different power consumption levels and different locking times can be generated by configuring a programmable charge pump (), a loop filter () parameter, a multi-path voltage-controlled oscillator () and a first multiplexer () corresponding thereto, a five-stage-division-by-two frequency division link () and a corresponding second multiplexer () and third multiplexer (), so as to implement generation of a multi-standard performance reconfigurable I/Q orthogonal carrier.
