Embodiment Construction

[0025] Numerous details are described herein in order to provide a thorough understanding of example implementations illustrated in the drawings. However, the invention may be practiced without many of the specific details. Well-known methods, components and circuits have not been described in exhaustive detail so as not to unnecessarily obscure more relevant aspects of the implementations described herein.

[0026] Antennas of wireless devices are used to transmit and receive radio frequency (RF) signals in frequency bands. Tuner circuits are often used to enable adjustable impedance matching between the transceiver and the antenna at selectable frequencies. Tuning generally refers to adjusting a component's main resonant frequency or a frequency-dependent value (eg, impedance) relative to the center frequency of the RF signal. More specifically, tuner circuits are typically used to provide impedance matching at the carrier frequency of the RF signal in order to improve pow...

Abstract

One implementation is capable of tuning a multi-band antenna such that two or more bands are tuned independently of each other, thereby decoupling tuning one band from tuning the other. Some implementations include a multi-band tuning device having a first tunable diac and a second tunable diac. The first tunable two-terminal circuit has a low transfer impedance associated with the first frequency band and a high transfer impedance associated with the second frequency band, the first tunable two-terminal circuit includes a first control element to selectively adjust the connection with the first frequency band. The frequency band is associated with the first resonant frequency. The second tunable two-terminal circuit has a high transfer impedance associated with the first frequency band and a low transfer impedance associated with the second frequency band, the second tunable circuit includes a second control element arranged to adjust the The second resonant frequency of the coupler.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 981,688, filed April 18, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to a wireless communication system, and in particular, to an antenna tuning device suitable for a multi-band wireless device. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, data and multimedia applications and services. These systems are typically configured to support communication with multiple users by sharing available system resources, such as designated portions of the spectrum. The continued popularity of high data rate wireless services continues to stimulate demand for access to the available spectrum. The ability to meet demand is often limited by the lack of available spectrum within a geographic area that ...
