GC5325 wideband digital pre-distortion transmit IC solution
ثبت نشده
چکیده
The Texas Instruments GC5325 wireless transmit processor integrates digital radio functionality previously only available in discrete devices. The GC5325 linearizes the output of the power amplifier (PA) in the transmit signal chain, thus removing the need for more costly high-performance PA components, improving the PA’s power efficiency and decreasing the overall power consumption of the base station. High-performance PAs can account for as much as 30 percent of the operational costs of a wireless base station in today’s cellular infrastructure. The GC5325 solution gives wireless equipment manufacturers the opportunity to reduce the overall cost of their RF subsystems.

متن کاملMemory Polynomial Based Adaptive Digital Pre- Distorter
Due to multicarrier propagation, newer transmission formats like WCDMA has high peak to average power ratio, which results the generation of IMD products at the output of the power amplifier (PA). To overcome this problem, we present a fast adaptive digital pre-distortion technique for Wideband Code Division Multiplexed systems by using Memory Polynomial function. The results show that the new ...
