ABSTRACT:
A frequency synthesizer (100) for use in combination with the transmitter (30) for transmitting guidance information to one or more ground launched active radar guided missiles simultaneously which is tunable to a plurality of frequencies separated by a predetermined interval. The frequency synthesizer (100) employs a phase-locked loop (110) having a phase detector (114) which receives input signals of common frequency from two dividers (112 and 124). Frequency control is achieved by varying the divisor of one of the dividers (112).
