Embodiment Construction

[0024] All the features disclosed in this specification, or all disclosed methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any manner.

[0025] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless specifically stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is just one example of a series of equivalent or similar features.

[0026] see figure 2 As shown, the radio frequency port is the radio frequency port of the radio frequency module. There is a microstrip line between the internal circuit of the radio frequency module and the radio frequency port. A wire is connected between the microstrip line of the radio frequency port and the ground to realize the antistatic effect of the radio frequency port. 0.2mm-1mm, the wire width is determined according to the layout area, but generally ...

Abstract

The invention discloses a method for realizing electrostatic prevention at a radio-frequency port. A wire is connected between a microstrip line of the radio-frequency port and the ground, the width of the wire is 0.2-1 mm, and the length is in a way of a quarter-wave line connected in parallel to the microstrip line. The invention effectively inhibits the static signal input to the radio-frequency port, thereby realizing the function of electrostatic prevention at a radio-frequency module port. The invention has the advantages of simple circuit, small size, low cost, simple method, easy realization and high effectiveness.

Description

Technical field [0001] The present invention relates to a radio frequency module, in particular to a method for the radio frequency module to realize anti-static of a radio frequency port. Background technique [0002] With the development of the field of radio frequency design, radio frequency applications have entered all areas of our lives, and the reliability design requirements of radio frequency modules have become higher and higher. As the most basic requirement of reliability design, anti-static design has also been increasingly subject to People pay attention to the fact that RF module designs in various fields now have port anti-static design requirements. [0003] The traditional anti-static method of the radio frequency port is mainly implemented by diode clamping. The diode is connected in parallel to the ground on the microstrip line of the radio frequency port. When the electrostatic signal is higher than a certain amplitude, the diode is turned on and the electrosta...
