The invention discloses a combining and dividing circuit structure of a receiver output port. The structure comprises a box body, also comprises an output port, a microwave band signal output straight-through circuit, a power supply input circuit and a 10MHz signal input circuit. The microwave band signal output straight-through circuit, the power input circuit and the 10MHz signal input circuit are sequentially connected; a microstrip circuit is connected between the output port and the microwave band signal output straight-through circuit. A high impedance circuit is connected to the microstrip circuit between the output port and the microwave band signal output straight-through circuit, the 10MH signal input circuit is connected to the end, away from the microstrip circuit, of the high impedance circuit, and the power input circuit is connected between the 10MHz signal input circuit and the microstrip circuit. The circuit structure can reduce the butt joint of the receiver, reduce the size of the receiver, simplify the equipment structure and the connection line, and facilitate the reduction of the cost of the receiver.
Description
technical field [0001] The invention relates to a combination and split circuit structure of an output port of a receiver, and belongs to the technical field of receivers. Background technique [0002] The superheterodyne receiver is a receiving device that uses locally generated oscillatory waves to mix with the input signal to convert the frequency of the input signal to a predetermined frequency. The performance of this receiving method is better than that of high-frequency (direct) amplified receiving, so it is still widely used in the receiving of long-distance signals, and has been extended to measurement technology and other aspects. [0003] In the equipment of the superheterodyne receiver, it is necessary to provide the frequency-converted radio frequency signal to the terminal equipment. signal to the receiver. At the same time, the superheterodyne receiver has strict requirements for miniaturization. If the three signals are connected to the receiver with three ...
