Abstract: The aim of the present work is to design and develop an RF Exciter in the VHF band frequency. The exciter provides pulse modulated Bi-phase coded RF signal at 53 MHz frequency. And it generates highly coherent Receiver local oscillator signal, as well as required auxiliary clock signal for synchronizing operations of all the sub-systems of the radar. The spectral performance of the 53MHz RF signal is achieved via use of quartz crystals in the Master Oscillator, and a variety of recently developed circuit technologies and frequency synthesis techniques.
