    • 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.
    • 提供一种脉冲调制型的毫米波发送/接收装置,其中由于内部反射或其他原因,防止用于发送的脉冲调制毫米波信号被输出到接收系统。 包括:由夹在平行板导体之间的介质线形成的NRD引导件(基本结构); 一个毫米波信号振荡器; 脉冲调制器; 循环器 发射/接收天线; 和搅拌机。 在混频器的输出端设置有一个在打开状态下中断中频信号的开关装置,并且当用于从脉冲调制器传输的毫米波信号进入非输出状态并且条件稳定时,改变 进入关闭状态以通过中频信号。 可以防止包含由进入混合器的传输的毫米波信号产生的噪声的中频信号向混合器的下游侧泄漏; 因此可以输出期望的中频信号。
