Radio frequency controller and a communication module having the same

A communication module comprising:

• a first component to be connected, wherein the first component to be connected is a printed circuit board;
• a second component to be connected, wherein the second component to be connected is another printed circuit board or a cavity filter;
• and
• a radio-frequency connector which is provided between the first and second components and connects the two to form a signal transmission loop, wherein the radio-frequency connector comprises:
• an outer conductor having a hollow housing with outer electrical contacts at its ends, wherein the outer conductor further comprises a conductive gasket and/or conductive glue that is placed in a recess formed at an end of the housing and works as the outer electrical contacts;
• and
• an inner conductor comprising a central body configured to be installed inside the outer conductor and spaced from the outer conductor with an annular space therebetween;
• wherein, in each end region of the central body of the inner conductor, an elastic connection assembly is provided for electrically connecting the central body to the first or the second component,
• wherein the elastic connection assembly comprises a male joint and a female joint which mate with each other to form an abutment connection, the male joint or the female joint having elasticity in a radial direction in the area of the abutment connection, one of the male joint and the female joint being provided on the central body, and the other of the male joint and the female joint being provided on the first or the second component, and
• wherein the central body of the inner conductor is directly connected to the first or the second component by means of the elastic connection assembly, without involving the outer conductor.
