Furthermore, while not shown for ease of illustration in FIG. 4, configuration information from control storage 250 may further be coupled to power amplifier 256 and RF filters 254, an antenna switch 257 and an antenna 258, to control these components as desired.

而且虽然为了图4描述简单，没有显示出来，来自控制存储器250的配置信息还可耦合到功率放大器256和射频滤波器254，天线开关257和天线258，以便根据需要来控制这些器件。

Mobile phone RF system consists mainly of transceivers, power amplifier and antenna switch. PA might be set in the Front-End-Module or FEM. In 2G, the cost of RF system was only about US $1.5, while In 3G, the cost was increased to between US$6.0 and US$8.0, and the cost will further increased to about US$8.0 to US$10.0 in 4G, obviously, FR system had the highest cost growth during the upgrading of mobile phones.

手机射频系统有三个主要零组件，收发器、功率放大器（Power Amplifier，下简称PA）和天线开关，有时PA包含在前端模块（Front-End-Module，简称FEM）。2G时代的射频系统只占大约1.5美元的成本，3G时代则占大约6-8美元的成本，4G时代则占大约8-10美元的成本，也是手机升级换代成本增加最多的部分。

We also design and manufacture communication systems based on our own power amplifiers.
