ことを特徴とする発振器。Mobile radio equipment has a voltage-controlled oscillator that becomes a transmitting frequency oscillator during transmission and a local oscillator during reception, and the output of a phase comparator that compares the output of the frequency divider with a reference signal that follows this is a low-pass P-wave oscillator. In the closed loop circuit, which becomes the input of the voltage controlled oscillator through a resistor, an element that determines the loop characteristics of the low-pass wave filter is connected to a transmitting/receiving switching signal and the above signal is connected to the other end of a capacitor whose one end is grounded through a resistor. An oscillator characterized in that a connected signal is switched by the output of a two-man NAND input.
