US08688063B2 Signal converting apparatus and receiving apparatus for supporting concurrent dual bands in wireless communication system 有权
用于在无线通信系统中支持并发双频带的信号转换装置和接收装置

Signal converting apparatus and receiving apparatus for supporting concurrent dual bands in wireless communication system
Abstract:
A receiving apparatus in a wireless communication system includes: an antenna configured to receive a wireless frequency signal including a first frequency band signal and a second frequency band signal; a low noise amplifier (LNA) configured to amplify the wireless frequency signal, output the first frequency band signal as a differential phase signal, and output the second frequency band signal as a common phase signal; a differentiator configured to pass only the differential phase signal between the signals outputted from the LNA; and a combiner configured to pass only the common phase signal between the signals outputted from the LNA.
Abstract(Chinese):

无线通信系统中的接收装置包括：天线，被配置为接收包括第一频带信号和第二频带信号的无线频率信号; 配置为放大无线频率信号的低噪声放大器（LNA），将第一频带信号输出为差分相位信号，并输出第二频带信号作为公共相位信号; 一个微分器，被配置为仅在所述LNA输出的信号之间通过所述差分相位信号; 以及组合器，其被配置为仅在从LNA输出的信号之间传递公共相位信号。
