We investigate intermodulation distortion of a tunable radio frequency photonic filter utilizing an optical frequency comb, an interferometric configuration, and a balanced detection. When the filter passband is tuned from 2 to 7 GHz, this scheme has the third-order spurious free dynamic range of <108.2 dB$\cdot $ Hz$^{\mathrm {2/3}}$ . In addition, we investigate the effect of Mach-Zehnder modulator...
For the first time, intermodulation distortion of micro-electromechanical capacitive switches in the actuated state was analyzed both theoretically and experimentally. The distortion, although higher than that of switches in the suspended state, was found to decrease with increasing bias voltage but to depend weakly on modulation frequencies between 55 kHz and 1.1 MHz. This dependence could be explained...
A packaged up-converter has been developed for the ETSI 42 GHz point-to-point radio band. The MMIC contains an LO-doubler-buffer amplifier, an image-reject balanced mixer and an RF variable gain amplifier. The up-converter has 10 dB conversion gain, 15 dB image rejection, 15 dB of gain control, 15 dBm IIP3 and 50 dB LO-to-RF isolation in the mixer. The up-converter consumes less than 1 watt DC represents...
We theoretically and experimentally evaluate the harmonic and intermodulation distortion in a SFL phase shifter which comprises an EOM, a SOA under CPO regime and an optical filter.
This paper presents a study on existing techniques on cancellation of strong interference in frequency bands adjacent to the radio receivers. It also proposed a new configuration for cancellation of this strong interference, merging techniques known with a new model developed. The idea is to build an end cancellation/attenuation interference of affordable sub-system, that is universal and adjustable...
