IMD (Intermodulation Distortion)

 The smaller the IM (Intermodulation) term, the better the function. In fact, the term used more often than the term IM, the so-called IM3, is actually IMD (Intermodulation Distortion). IMD means the distortion signal or the magnitude of the distortion signal. The original conceptual definition of IMD refers to the magnitude of the IMD, expressed in dBc with the minus sign for the difference between the two signals.

The causes of PIMD value of RF components are classified into contact nonlinearity and material nonlinearity.

The causes of contact nonlinearity include the bonding capacity of thin oxide layers between conductors, the tunneling effect of semiconductor action between conductors in metal contact, the voids and microcracks between metals, and the Nonlinearity associated with dust and metal particles.

Among them, the tunneling effect, which is a fundamental characteristic of IM generation, is determined by the nonlinear resistance and capacitance of the RF flow region. Here, the nonlinear junction resistance increases with time, which may be caused by interface diffusion, impurity adsorption, edge effect, and mechanical rupture.

In order to solve many of these problems, a functional broadband connector for an antenna of the present invention has been developed.

As described above, the present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely exemplary, and it should be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. will be. Therefore, the true technical protection scope of the present invention will be defined by the technical details of the appended claims.
