收发器

Backplane Transceiver Logic is a signaling standard that was invented and first introduced by National Semicon- ductor, then developed by the IEEE to enhance the perfor- mance of backplane buses.

背板收发器逻辑的是一个信号标准，这是首次由国家发明和半导体，矽晶片介绍，然后由IEEE开发，以提高perfor -背板巴士曼斯。

During the design of VXI-bus Serial Controller Module, the functions of VXI-bus including time-sequence for VXI interface, resource management, interrupt process, bus arbitration, are accomplished. To advance the performance and stability, the FPGA technic is used to implement the kerneled code including serial bus time-sequence switching to VXI interface time-sequence, the UART, the Parameterized Baud Generator and"Pipeling frame". The handle type of Data Transfer Bus for VXI-bus is researched thoroughly, and the format of serial data transfer is designed.

在VXI总线串行控制器设计中，实现了VXI总线控制器的基本功能，包括VXI总线接口时序、总线仲裁、超时处理等；同时利用先进的FPGA技术实现了串行总线时序向VXI总线时序的转换、通用异步收发器、参数化波特率发生器、流水线结构等功能模块；在设计中还深入研究了VXI总线数据传输的各种操作类型，制定了串行数据传输的编码格式。

The first hubs were known as "multiport transceivers" or "fanouts".

第一个集线器被认为是&多端口收发器&或者叫做&fanouts&。

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。

Antenna switch is also has high entry barriers. Although its price is rather lower than PA and receiver, usually requiring SiP packaing and LTCC underlay. Globally, antenna switches are mainly supplied by Japanese vendors such as MURATA, Renesas and New JRC etc.

天线开关也是一个高门槛领域，虽然其价格远低于PA和收发器，通常要使用LTCC衬底和SiP封装，全球主要由日本厂家供应，有村田、瑞萨和新日本无线。
