Abstract :
This article describes the development and construction of an evolutional SHF band signal receiving and transmission system using an optical modulator that operates via a faint signal in the 3.4GHz band. The modulator is a LiNbO3 optical modulator of Mach-Zehnder type, which can be used to modulate a light beam at 1.5 μm with FM signals at 3.4GHz band and a voltage level of 60dBμV from a receiving antenna. Performance was satisfactory.
