Embodiment Construction

[0039] Subheadings, if any, are provided here for convenience only and do not necessarily affect the scope or meaning of the claimed invention.

[0040] introduction

[0041] To improve power transfer between circuit elements, it is generally desirable to select elements with matched impedances. However, in some cases circuit elements may be designed with different impedance values. Furthermore, in some cases environmental factors such as the location of devices may affect the impedance of circuit elements. Including components with mismatched impedances reduces power transfer between circuit elements. For example, a mismatch between the impedance of the antenna and the amplifier circuit or transceiver may result in reduced power transfer between the antenna and the amplifier circuit or transceiver. One solution to the impedance mismatch problem is to use an impedance matching circuit between circuit elements, which can be used to match the impedance of two circuit elemen...

Abstract

An L-shaped dynamically configurable impedance matching circuit is presented herein. The circuit can include a series element and a shunt element. The shunt element in the L-shaped impedance matching circuit can be moved or modified based on the impedance of the circuit elements in electrical communication with each side of the impedance matching circuit. Thus, in some cases, the impedance matching circuit may be a flexible circuit that can be dynamically modified based on the environment or configuration of the wireless device that includes the impedance matching circuit.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 841,217, filed June 28, 2013, and entitled "FLEXIBLEL-NETWORKANTENNATUNER CIRCUIT," the disclosure of which is expressly incorporated herein by reference in its entirety. technical field [0003] This application relates generally to impedance matching elements. More specifically, the present application relates to flexible and tunable impedance matching elements. Background technique [0004] Radio frequency (RF) switches, such as transistor switches, may be used to switch signals between one or more poles and one or more throws. Transistor switches, or portions thereof, may be controlled by transistor biasing and / or coupling. The design and use of biasing and / or coupling circuits associated with RF switches can affect switch performance. [0005] In some cases, circuit elements may produce different impedance values. In order to improve the per...
