Embodiment Construction

[0023] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0024] The invention provides a miniaturized multiplexer, which includes a metal shell, a signal input port installed on the metal shell, multiple signal output ports, and multiple spiral resonators installed in the metal shell. The metal shell is used to support the helical resonator in the multiplexer, and at the same time, energy loss can be reduced because the helical resonator is in the cavity of the closed metal shell.

[0025] A spiral resonator is electrically connected with a signal output port, and is used to output a signal of a specific frequency through each signal output port after processing the external signal input by the signal input ...

Abstract

The invention discloses a miniaturized multiplexer. The miniaturized multiplexer comprises a metal shell, a signal input port, a plurality of signal output ports and a plurality of spiral resonators,wherein the signal input port and the signal output ports are formed in the metal shell; the spiral resonators are arranged in the metal shell; the plurality of spiral resonators are electrically connected with the signal input port, and each spiral resonator is electrically connected with one corresponding signal output port; the signal input port is used for inputting an external signal and transmitting the external signal to each spiral resonator, so the signal with a corresponding frequency in the external signal is transmitted out through the corresponding signal output port under the resonance effect of each spiral resonator; and a metal wall is arranged between every two adjacent spiral resonators and is used for isolating signals between the adjacent spiral resonators. The multiplexer provided by the invention has the characteristics of high isolation, small size, simple structure and the like.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a miniaturized multiplexer. Background technique [0002] A multiplexer is used to transmit signals of different frequency bands to different channels. It is usually used to separate the receiving and transmitting signals of a common antenna. At the same time, the multiplexer can also be used as an isolation device to connect the receiving circuit and the transmitting circuit. Generally speaking, there are two connection methods for the multiplexer at the RF front end: one is a single-port input or output signal, and the other port is connected to the transceiver antenna; the other is one end is connected to a multi-band antenna, and the other port is connected to a multi-signal communication port. The above connection method can effectively reduce the volume of the radio frequency front-end, but has relatively high requirements on the performance of the antenna, that is, r...
