摘要： Provided is a millimeter-wave transmitting/receiving apparatus of pulse-modulation type in which pulse-modulated millimeter-wave signals for transmission are prevented from being outputted to a reception system due to inner reflection or other causes. Included are: an NRD guide (basic structure) formed of a dielectric line sandwiched between parallel plate conductors; a millimeter-wave signal oscillator; a pulse modulator; a circulator; a transmitting/receiving antenna; and a mixer. At the output end of the mixer is disposed a switching device which interrupts intermediate-frequency signals in an opened state, and, when a millimeter-wave signal for transmission from the pulse modulator enters a non-output state and the condition is stabilized, changes into a closed state to pass intermediate-frequency signals. The intermediate-frequency signal containing noise resulting from the millimeter-wave signal for transmission entering the mixer can be prevented from leaking toward downstream side of the mixer; wherefore a desired intermediate-frequency signal can be outputted.

摘要： A millimeter-wave transmitter-receiver uses an NRD guide as a fundamental configuration and includes a millimeter-wave signal oscillator, a pulse modulator, a circulator, an antenna and a mixer. In the millimeter-wave transmitter-receiver, a line length of a third dielectric guide is set so that δ=±π in which δ is a phase difference at a center frequency between a portion of a transmission millimeter-wave signal, which is reflected via a third dielectric guide on the leading end portion of the third dielectric guide and returned to leak to a third connecting portion of the circulator, and another portion of the millimeter-wave signal, which leaks from a first connecting portion to the third connecting portion of the circulator. It is possible to reduce the change in the mixer output and enhance the millimeter-wave transmission/reception performance.
