The present application relates to the field of microwave photonics, and more particularly to a high linearity microwave photonics down-conversion receiving system based on an optoelectronic oscillator. The system comprises a laser, a first phase modulator, a first optical amplifier, a phase-shifted Bragg grating, a first photodetector, a second phase modulator, an optical filter, a second optical amplifier, and a second photodetector. The frequency of the local oscillator signal generated by the first photodetector can be tuned by changing the frequency of the laser, thereby effectively realizing the tuning of the down-converted signal output by the second photodetector. By adjusting the gain value of the first optical amplifier, the amplitude of the local oscillator spectral harmonic in the output optical signal of the first phase modulator is a specific value, thereby realizing the suppression of the third-order intermodulation distortion in the output signal, and further improving the spurious-free dynamic range of the entire down-conversion receiving system.

The application belongs to the field of microwave technology and discloses a reconfigurable differential filter based on HMCSIW, which comprises a first layer metal layer, a first layer dielectric layer, a second layer metal layer, a second layer dielectric layer and a third layer metal layer, the first layer metal layer is composed of a rectangular patch of a half-mode combline, a pair of trapezoidal microstrip lines, a pair of open-circuit microstrip stubs and a DBCSRR structure, the second layer metal layer is composed of a rectangular slot and a folded SSPPs structure and is a common ground of the structure, and the third layer metal layer is completely consistent with the structure size of the first layer metal layer. The length of the open-circuit stubs connected in parallel on the HMCSIW is controlled by the conduction and shutdown of the PIN diode, so that the resonant frequency of the open-circuit stubs is controlled, then the low-frequency zero point of the filter will change, and the bandwidth and center frequency of the entire filter will change accordingly. The filter can be reconfigured and combined with the differential transmission line, and has a common-mode rejection characteristic.
