Specific embodiment
Effect for making to architectural feature of the present utility model and reached has a better understanding and awareness, in order to relatively
Good embodiment and accompanying drawing cooperation detailed description, are described as follows:
Existing feeder line assembly structure as shown in figure 1, its feeder line assembly by four-terminal circulator, bonder, flexible waveguide, load,
Low noise sound field is put and is switched composition with pin.Its work has transmitting and receives two kinds of working conditions: during transmitting working condition, radio frequency is believed
Number aerial radiation is passed to through four-terminal circulator by transmitter, under this working condition, pin switch is off state, prevents high-power
Signal passes to low noise sound field to be put and burns field and put or receiver；When receiving working condition, radiofrequency signal is received by antenna, through four ends
Circulator passes to pin switch and low noise sound field is put.Under this working condition, pin switch is in the conduction state, puts through low noise sound field
Receiver is delivered to after big.
It is existing that we need to test, in the state of high/low temperature circulation, the gain being put passage by antenna receiving port to low noise sound field
