Claims

[Scope of utility model registration request]

(1) In a radiotelephone device that communicates between a transmitter that sends a pilot signal during transmission and a receiver that receives the pilot signal and performs reception under control of the pilot signal, the pilot signal detection unit of the receiver A reception stop delay circuit is inserted in the transmitter, and even after the pilot signal is no longer supplied, reception continues for the delay time of the reception stop delay circuit, a delay circuit is inserted in the transmitter, and the transmission switch of the transmitter is turned off. A wireless telephone device that transmits a carrier wave for a delay time of a delay circuit of the transmitter even after the transmission.

(2) The delay circuit of the transmitter includes a transistor and a capacitor, and when the transmission switch is operated, the transistor conducts to supply power to the transmitter and charge the capacitor;
2. The wireless telephone device according to claim 1, wherein when the transmission switch is turned off, the transistor is made conductive by the discharge current of the charged capacitor, and the transmitter continues to operate.
