By
Progress In Electromagnetics Research, Vol. 139, 761-777, 2013
Abstract
A new circuit and technique to extend bandwidth performance while preserving improvement on efficiency performance over the one attainable by conventional distributed amplifier (DA) 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 ~29 dBm, gain of 10 dB, covering a bandwidth from 100 to 800 MHz, PAE of 20-45% is experimentally demonstrated. The result is compared with measured result of conventional DA, a significant improvement of bandwidth and efficiency are achieved.
