ABSTRACT OF THE DISCLOSURE A frequency synthesizer for use in a transmitter/re- ceiver, comprising a voltage controlled oscillator, a programmable frequency divider for dividing the frequency of the output from the voltage controlled oscillator, a reference oscillator, a reference counter for dividing the frequency of the output from the reference oscillator, a phase detector for phase detecting the frequencies of the reference counter and the frequency divider for providing a control voltage to the voltage controlled oscilla- tor, a transmitting/receiving mode selection circuit for selec- tively controlling the programmable frequency divider such that the frequency division rate thereof is different in the trans- mitting and receiving modes, a channel designating circuit, a first output terminal for withdrawing an output by mixing the output from the voltage controlled oscillator with the output from the reference oscillator, and a second output terminal for directly withdrawing the output from the voltage controlled oscillator, said transmitting/receiving mode selection circuit comprising a transmitter/receiver selection switch, and full adder means or a read only memory for storing in advance, informa- tion concerning the frequency division rate of the frequency divider based on the output from the transmitter/receiver selection switch and the output from the channel designating circuit.
