Embodiment Construction
[0032] Such as Figure 1-3 As shown, a microwave signal coupling device includes a microstrip plate 7, a transmission microstrip 4, a coupler 1, a distributor 2, a π attenuator 5, a detector V1, a filter circuit 6, a grounding microstrip 3, and a resistor R6. Transmission microstrip 4 , coupler 1 , distributor 2 , π attenuator 5 , detector V1 , filter circuit 6 , grounding microstrip 3 , and resistor R6 are all arranged on microstrip board 7 .
[0033] The distributor 2 includes a first output terminal and a second output terminal of the distributor, and an isolation resistor R1 is arranged between the first output terminal and the second output terminal of the distributor. Distributor 2 can include multiple output ports, so that multiple coupled signals can be output. Optimally, in this solution, distributor 2 is a 1:2 distributor, which has a simple structure and can realize coupled signals, continuous or pulse The voltage signal is output as two channels respectively. The...

A microwave signal coupling apparatus comprises a micro-strip plate, a transmission microstrip, a coupler, a distributor, a pi attenuator, a detector V1, a filter circuit, a grounding microstrip and a resistor R6. An isolation resistor R1 is arranged between a first output terminal and a second output terminal of the distributor. The coupler comprises an input terminal and three output terminals. The three output terminals are a first output terminal of the coupler, a second output terminal of the coupler and a third output terminal of the coupler. A first input terminal of the coupler is taken as an input terminal of the whole apparatus. The second output terminal of the coupler is taken as a first output terminal of the whole apparatus. The second output terminal of the coupler is connected to an input terminal of the distributor. The first output terminal of the distributor is taken as a second output terminal of the apparatus. The second output terminal of the distributor, an input terminal of the pi attenuator, an output terminal of the pi attenuator, the detector V1 and an input terminal of the filter circuit are successively connected in series through the transmission microstrip. The apparatus has advantages of advanced functions, reliable quality, convenient usage and a wide suitable range.
