Abstract
For the urgent demand of the broadband, high efficient, parallel processing and anti-jamming capability in the field of ultra-wideband measurement control and communication. This paper puts forward a kind of channelized receive technology based on microwave photonic technology. The coherent optical comb generation module generates the signal optical comb and the local oscillator optical comb. The coherent optical comb with high repetition frequency is obtained by using cascade modulator and nonlinear technique. In order to satisfy the 10 comb tooth designed for the system, the FSR of coherent optical frequency comb is greater than 100GHz and 99.4GHz respectively, and the channel bandwidth is 600MHz. The channel division module receives the broadband RF signal from the RF front-end and modulates it to the optical frequency comb. By DPMZM single sideband modulation, 10 optical combs can be used to shift the frequency of the oscillator frequency comb. At the same time, according to the position of the 6GHz signal, the frequency comb is accurate controlled. After the WDM multiplexing device, it is selected by the high-speed optical switch controlled by the control unit. The photoelectric detection and mirror frequency suppression are realized by coherent demodulation, which consists of an optical mixer, a balance detector and a bridge. Which realizes channelized reception and cross-frequency conversion of any 6GHz wideband signal from the DC to 40 GHz band. Achieve 3dB channel consistency and mirror frequency suppression above 30dB. The results are verified by simulation and experiment. This method can also be extended to receive ultra-high speed frequency hopping signals. Which can provides technical support for ultra-wideband measurement control and communication, integrated RF front-end and electromagnetic space integration system.
