Abstract

The invention provides a microstrip isolator, which can ensure sufficient grounding of the isolator and an external circuit, thereby ensuring normal operations of the isolator. The microstrip isolator comprises a cylinder with a cover, a base plate and a resistor, wherein the circumferential surface of the cylinder with a cover is provided with avoidance slots, the bottom part of the cylinder with a cover is fixedly installed on the base plate, a cavity formed by combining the cylinder with a cover and the base plate is internally provided with an intracavity element, the intracavity element comprises a circuit portion, three outward protruding pins of the circuit portion penetrate through the corresponding avoidance slots, and the tail end of one of the pins is externally connected with the resistor. The microstrip isolator is characterized in that the base plate is specifically of a metal-plastic mixed material structure, the base plate is provided with metal connecting portions at positions corresponding to fixedly installed portions of the cylinder with a cover, the base plate is provided with a central metal connecting region at the central position, and each metal connecting portion is connected to the central metal connecting region through a metal wire / metal strip embedded in the plastic.

Description

technical field

[0001] The invention relates to the technical field of wireless communication equipment, in particular to a microstrip isolator. Background technique

[0002] In the existing wireless communication system, the transmitter is an important part, which is composed of a power amplifier (PA), a coupler, a circulator / isolator, a connector, a duplexer and an antenna, among which the coupler is used For the related monitoring function of the link, the circulator or isolator is used to protect the power amplifier tube, and the connector transmits the output signal to the duplexer. It is a similar design in the wireless field, but with the development of wireless communication, the requirements for miniaturization are getting higher and higher.

[0003] In the prior art, the microstrip isolator includes a cylinder with a cover, a bottom plate, and a resistor. The cylinder with a cover is covered on the bottom plate, and the inner cavity of the cylinder with a cover is...
