Abstract

PURPOSE:To reduce the number of local oscillators which are required as many as the number of switching times of transmission frequencies to half by using an upper and a lower side bands which are obtained by mixing two signals together when transmission frequencies are switched, and using selectively both bands through a filter of each band. CONSTITUTION:The output signal of a transmitting mixer 3 includes the upper and lower wave bands of the mixture output of a local oscillation signal and a transmit original signal; FH=fL+fC and FL=fL-fC, where FH and FL are their frequencies. When the transmission frequency fH is selected, a changeover switch A2-11 and a changeover switch B2-12 are set at sides of a filter A5-11 to select FH for a transmit signal; when the transmission frequency FL is selected, the changeover switches A2-11 and B2-12 are set on sides of a filter B5-12 to pass a transmit signal of FL selectively. Pulse modulation is imposed on the transmit signal by a power amplifier 6 and the modulated signal is amplified to be radiated into the space from an antenna 10 through a transmission/reception switch 9.
