摘要：

A new circuit and technique to extend the bandwidth of the Dual Fed Distributed Amplifier (DFDA) while preserving the improvement on efficiency performance in comparison to conventional distributed amplifiers (DAs) is presented. The theoretical analysis is described in detail, and a test vehicle is realized to demonstrate the effectiveness of the proposed method. Output power of similar to 29 dBm, gain of 10 dB, covering a bandwidth from 100 to 800 MHz, with a PAE of 20- 45% is experimentally demonstrated. The results are compared with measured results of the conventional DA, demonstrating a significant improvement in bandwidth and efficiency.
