摘　　要：The development of a high performance wideband radio frequency （RF） transceiver used in the next generation mobile communication system is presented. The developed RF transceiver operates in the 6 to 6.3 GHz band and the channel bandwidth is up to 100 MHz. It operates in the time division duplex （TDD） mode and supports the multiple-input multipleoutput （MIMO） technique for the international mobile telecommunications （IMT）-advanced systems. The classical superheterodyne scheme is employed to achieve optimal performance. Design issues of the essential components such as low noise amplifier, power amplifier and local oscillators are described in detail. Measurement results show that the maximum linear output power of the RF transceiver is above 23 dBm, and the gain and noise figure of the low noise amplifier is around 24 dB and below 1 dB, respectively. Furthermore, the error vector magnitude （EVM） measurement shows that the performance of the developed RF transceiver is well beyond the requirements of the long term evolution （LTE）-advanced system. With up to 8 x 8 MIMO configuration, the RF transceiver supports more than a 1 Gbit/s data rate in field tests.介绍了一种应用于下一代移动通信系统的高性能宽带射频收发信机的实现.本射频收发信机工作在6～6.3GHz频段,信道带宽达到100MHz,工作在时分双工模式并支持IMT-advanced系统采用的多输入多输出(MIMO)技术.为了获得最佳的性能,采用了经典的超外差结构.详细介绍了系统关键部件如低噪声放大器、功率放大器以及本地振荡器的设计问题.测试结果表明,射频收发信机的最大线性输出功率大于23dBm,低噪声放大器的增益和噪声系数分别为大约24dB和小于1dB.此外,误差矢量幅度(EVM)的测试结果表明实现的射频收发信机的性能远超过LTE-advanced系统的要求.采用最大8×8的MIMO配置,本射频收发信机在现场试验中支持超过1Gbit/s的数据传输率.
