Apparatus for optionally supporting time division duplex and frequency division duplex in a wireless communication system
Abstract:
A Radio Frequency (RF) front-end apparatus in a wireless communication system is provided. The apparatus includes a plurality of BandPass Filters (BPFs) for band-pass filtering a transmission signal or a reception signal, at least one circulator for dividing a signal transmission path and a signal reception path and at least one switch for controlling the signal transmission path and the signal reception path. The RF front-end apparatus provided by the present invention supports various frequency bands and optionally supports TDD and FDD in a wireless communication system.
Abstract(Chinese):

提供了一种无线通信系统中的射频（RF）前端装置。 该装置包括用于对传输信号或接收信号进行带通滤波的多个带通滤波器（BPF），用于分割信号传输路径的至少一个环行器和信号接收路径，以及用于控制信号传输路径的至少一个开关 和信号接收路径。 由本发明提供的RF前端装置支持各种频带，并且可选地在无线通信系统中支持TDD和FDD。
