The development of a broadband MIMO RF transmitter fulfilling the requirements of the IMT-Advanced wireless communication system is presented. The channel bandwidth of the transmitter is 100 MHz operating in the TDD mode with more than 25 dBm linear output power and 60 dB output power control range. Excellent EVM performance is obtained. The RF transmitter can support up to 6 × 6 MIMO configuration and has been successfully integrated with the MIMO RF receiver and the baseband modules. The average data rate in the field test is approximately 1 Gbps. [ABSTRACT FROM AUTHOR]

The article discusses the development of the compact radio frequency (RF) front-end system that meets the transmit and receive multimode requirement in software-defined-radio (SDR) picocellular base stations. It notes that the picocell systems provide multiple wireless access services for passengers onboard commercial aircraft. It tells that the experimental design has shown excellent linearity and phase-noise with outstanding error-vector magnitude (EVM) performance.
