Switch module and single-pole double-throw module in wireless communication

Abstract

The disclosed switch module and single-pole double-throw module for wireless communication is composed of a multi-layer board structure with increased layers, and passive elements. The multi-layer board structure with increased layers possesses multiple conducting layers and multiple dielectric layers superposed each other. There is at least any one dielectric layer between any two conducting layers. A passive element is as part of at least one conducting layer, and is electrical connected to multiple current conducting pads on at least one surface of multi-layer board structure with increased layers. The invention integrates capacitance, inductance and resistance etc, passive elements needed by switch circuit in radio frequency onto multi-layer board. Being applicable to front end module in radio frequency in electronic products of wireless communication, the invention reaches to purposes of lowering cost, and miniaturization.

Description

technical field [0001] The invention relates to a structure of a wireless communication switch, and in particular provides a switch module and a single-pole double-throw module for wireless communication using a build-up multilayer board to make a radio frequency switch. Background technique [0002] Low cost and miniaturization have become one of the important goals of wireless communications, digital computers, and portable electronic products. For example, the RF switch of the RF Front End Module controls the selection of the antenna, the switching between the antenna end and the receiving end, and the switching between the antenna end and the transmitting end, so it is one of the key components of wireless communication. [0003] The RF switch is composed of several ICs and passive components. The current limited passive components of the RF switch are surface mount components. Therefore, even if the circuit layout is changed, the usable area of ​​the circuit board canno...

AI Technical Summary

Problems solved by technology

[0003] The RF switch is composed of several ICs and passive components. The current limited passive components of the RF switch are surface mount components. Therefore, even if the circuit layout is changed, the usable area of ​​the circuit board cannot be effectively reduced, which is of limited benefit to the miniaturization of the product.
