The frequency compounding controller(100) decides the dividing ratio of the variable divider(90) dividing the signal output from the double band voltage controlling oscillator(80) and varies the dividing ratio of the variable divider(90) by selecting the frequency band of the double band voltage controlling oscillator(80) and the signal divided by the variable divider(90) is input to the phase detector(60). The reference signal generated by the reference signal generator(40) is input to the phase detector(60) with being divided by the reference divider(50).

Abstract: PURPOSE: A dual band wireless switching circuit is provided to separate a GSM receiving signal from a DCS receiving signal, and to input the separated signals to a GSM transmitting/receiving signal switching unit and a DCS transmitting/receiving signal switching unit, thereby clearly switching DCS transmission and reception signals without loss. CONSTITUTION: An antenna(300) transmits and receives GSM and DCS signals. A diplexer(310) transmits the signals to the antenna(300), and separates a GSM receiving signal from a DCS receiving signal. A GSM transmission signal detector(320) filters and detects a GSM transmission signal. The first switching voltage input unit(330) inputs the first switching voltage, and enables the detector(320) to detect the GSM transmission signal. A GSM transmitting/receiving signal switching unit(340) transmits the GSM transmission signal to the diplexer(310) when inputting the first switching voltage to the input unit(330), and separately outputs the separated GSM receiving signal when not-inputting the voltage. A DCS transmission signal detector(350) filters and detects a DCS transmission signal. The second switching voltage input unit(360) detects a DCS transmission signal by the detector(350). A DCS transmitting/receiving signal switching unit(370) transmits the DCS transmission signal when inputting the second switching voltage, and separately outputs the DCS receiving signal when not-inputting the voltage.
