In order to satisfy the requirements for promising communication and radar systems a new concept to design a multi-octave radio frequency (RF) synthesizer that is one of the crucial radio engineering means in demand, is proposed and discussed. In general, the concept is related to the application of the microwave photonics technique to realize the signal processing in super wideband optical range. Using this technique, the approach is referred to intermediate optical signal processing based on optical frequency comb including two optical recirculation loops that operate in the opposite directions of the frequency domain and narrow-band spectral demultiplexers for the needed frequency selection. To verify the concept possibility and efficiency, Cadence AWRDE simulation of RF synthesizer in C-to-W IEEE RF bands with a tuning interval of 4.25 GHz was successfully carried out. In the result, the microwave photonics-based RF synthesizer has been developed is able to operate in the band of more than 4 octaves with approximately the same output power of 4-5 dBm and the higher harmonics’ suppression of more than 30 dB.
