“…Although the RF and LO leakages are greatly suppressed, the harmonic spurs, such as 2ω RF and 2ω L O , are still inevitable which are produced by frequency beat of ±1st-order RF/LO sidebands. Therefore, the carrier-suppressed single-sideband modulation (CS-SSB) based microwave photonic mixers are presented to further suppress these mixing spurs [11]- [15]. Optical bandpass filter (OBPF) can be commonly used to filter out one of the sidebands [11]- [13].…”

A microwave photonic mixer based on a frequency-doubled local oscillator (LO) is proposed. The carrier-suppressed single-sideband (CS-SSB) modulation of the -first-order radio frequency (RF) and +second-order LO sidebands can be generated by using a dualpolarization dual-parallel Mach-Zehnder modulator (DP-DPMZM), an electrical 90°hybrid coupler, and an optical bandpass filter. The upconverted intermediate frequency (IF) signal with the frequency of ω R F + 2ω L O is output by frequency beat at a photodetector. Meanwhile, the -first-order RF sideband can be easily changed to +first-order RF sideband by adjusting one dc bias voltage of the DP-DPMZM. The downconverted IF signal with the frequency of ω R F − 2ω L O is obtained correspondingly. The experimental results show that the spur suppression ratios of upconverted and downconverted IF signal are 19.0 dB and 25.5 dB, respectively. The spurious-free dynamic range of the proposed mixer is 96.5 dB•Hz 2/3 . The output electrical spectrums are pure owing to the optimal design of the CS-SSB modulation. The proposed mixer reduces the frequency requirement of LO signal since the second-order LO single sideband is used, and the upconversion and downconversion can be switched to each other by a simple electrical operation.

A full-band direct-conversion receiver using a microwave photonic in-phase and quadrature (I/Q) mixer is proposed and experimentally evaluated in terms of radio frequency (RF) range, port isolation, phase imbalance, conversion gain, noise figure, spurious-free dynamic range, and error vector magnitude. The proposed microwave photonic I/Q mixer shows significant advantages in local oscillator leakage and I/Q phase imbalance over entire RF bands, which are recognized as major drawbacks of conventional direct-conversion receivers.OCIS The growing use of the radio spectrum requires electronic systems to operate at extended radio-frequency (RF) bands and signal bandwidth, putting forward great challenges to the RF receiver design. Microwave photonic techniques are recently introduced to overcome these limitations due to several inherent advantages, such as potential full-band operation, large instantaneous bandwidth, high RF isolation, low-loss transmission, and electromagnetic interference immunity [1][2][3] . As for frequency conversion that is a crucial function in an RF receiver, several microwave photonic schemes have been studied. A photonic method for wideband tunable RF conversion was presented by Harris Corporation [4] . With different photodetection fashions, a reconfigurable photonic microwave mixer was proposed [5]
