Abstract: PURPOSE: A multi-function circuit which is operated as a frequency mixer and an attenuator is provided to remove an additional unit such as a switch by simplifying a configuration in comparison with a conventional receiver. CONSTITUTION: A control voltage application unit(210) applies a control voltage controlling the operation mode of a signal processing unit. A choke coil(220) is electrically connected to the control voltage application unit. The choke coil prevents the inflow of a sine wave signal to the control voltage application unit. First and second diodes(230,240) are electrically connected to the choke coil and connected in parallel with each other while having opposition direction. An open stub(250) is electrically connected to one end of the first and second diodes. A short circuit stub(260) is electrically connected to the other end of the first and second diodes. A local oscillator(270) runs the first and second diodes.
