Embodiment Construction

[0037] Embodiments of the present invention will be described in terms of a wireless communication unit, such as user equipment, which includes an antenna port operatively coupled to at least one transceiver to the antenna. However, those skilled in the art will appreciate that the inventive concepts described herein may be implemented in any type of wireless communication unit, which may include a transceiver, such as a base station. Embodiments of the present invention describe in terms of a wireless communication unit capable of reconfigurable phase shifting, and more specifically, an RF transceiver module comprising a reconfigurable (eg, tunable) duplexer. In this way, when implementing a reconfigurable duplexer, the duplexer can simplify the front-end design and reduce the performance requirements of some RF components, because it is possible to adjust a certain frequency band or multiple frequency bands to the desired narrowband channel . In some instances, a reconfigur...

Abstract

The invention provides a wireless communication unit, a method for tuning the wireless communication unit and a radio frequency module. The wireless communication unit comprises at least one antenna port and an emitter and a receiver are coupled to the at least one antenna port operably through a duplexer. The duplexer comprises a dynamically reconfigurable phase-shift network, at least one tunable radio frequency element and at least one switch which is coupled to the tunable radio frequency element operably, wherein the switch can controllably reconfigure the dynamically reconfigurable phase-shift network through radio frequency signals of the dynamically reconfigurable phase-shift network and the operations of positive and reverse duplexing modes can be supported simultaneously and selectively. According to the invention, the wireless communication unit, the method for tuning the wireless communication unit and the radio frequency module can reduce complexity.

Description

[0001] 【cross reference】 [0002] This application claims priority to US Provisional Application No. 61 / 813717, filed April 19, 2013, which is incorporated herein by reference in its entirety. [0003] 【Technical field】 [0004] The present invention relates to radio frequency (RF) modules of wireless communication units capable of reconfigurable phase shifting incorporation, and more particularly to transceiver modules including reconfigurable duplexers. [0005] 【Background technique】 [0006] Wireless communication units, such as portable radios, telephones, etc., typically support operation at a single radio frequency (RF) frequency band, the operating frequency band used in the communication system. However, due to the rapid development of mobile communications, the spectrum needed to support a considerable number of various radio frequency standards, systems and services is now available to mobile users. Furthermore, radio frequency (RF) communication systems have evolv...
