Claims

[Claims for Utility Model Registration] A high frequency signal and a local oscillation signal are given to a mixer diode through a common band-pass transducer, and a signal with a frequency of the sum or difference of the two signals is passed through a band-elimination transducer to an intermediate frequency signal. In a microwave band frequency converter that outputs a signal, the bandpass transducer has three 18-wavelength stubs with one end grounded and the other end open, and the resonance frequency is the center frequency of the passband. It is composed of a stub-type reactor wave generator that includes two lines that are coupled in sequence, and the connection position between the stub and the line is such that the center frequency is higher than the ground end of each stub for the two stubs at both ends. It is approximately 176 wavelengths of the wavelength of the center frequency, and for the stub in the center, it is approximately 176 wavelengths of the wavelength of the above center frequency from the grounded end.
The length of the two lines is 1/8 wavelength at the center frequency, and the band-stop transducer is open at the other end and has a length of 174 wavelengths at the center frequency. A plurality of stubs are connected at intervals of 1/4 wavelength to the transmission line that couples the input and output ends, and a plurality of stubs with the other end open and having a length of 1/8 wavelength at the center frequency are connected to the transmission line that couples the input and output ends. A frequency converter characterized by a configuration in which it is connected to a transmission line at intervals of 178 wavelengths.
