This paper presents an experimental study on the design and manufacture of a mixed ultra-high frequency signal generator with a comb shape frequency-amplitude spectrum (Comb generator) with an ultra-wide working band covering from VHF band to the X band. The principled of creating harmonics using step recovery diodes (SRD) and the results of design and fabrication of comb tooth signal generators with a preselected harmonic frequency interval of 100MHz are presented. The transmitter includes 4 optional controllable outputs: A channel: 0.1-2GHz; B channel: 2-4GHz; C Channel: 48GHz and D Channel: 8-12GHz are used to automatically check the operation of wideband multichannel receivers of passive radar reconnaissance and radio navigation systems. Some empirical evaluations and extensibility of the design with reality applications are also introduced.
