【摘要】 相互混频式收发信机用一个稳定振荡源兼作发射源和接收机本振,调制采用直接调频方式,接收机部分采用直接混频方式,可采用频分、时分或码分方法从相互混频后产生的收发复合信号中分离出接收信号,收发信频率可选在微波频段的收发隔离带。更多还原

【Abstract】 A Stable oscillator acts as both transmission and receiving local oscillator in the mutual mixing type microwave transceiver.Direct FM and direct mixing method are used here. Frequency devision,time division or code division may be used to separate receiving signal from the mixed signal produced by reciprocal mixing.The working frequency can be assigned locating between the transmitting and receiving band of some microwave band.更多还原
