In this thesis work, a new distributed amplifier topology is discussed and applied to three different cases. The topology is based on dividing the frequency spectrum into channels and amplifying afterwards. The channelized and amplified signals are then combined at the output for broadband amplification. This topology is used in the design of a three channel 0.1-1 GHz amplifier with a gain of 14.5±0.6 dB. The design is fabricated, and then the measured and simulated results are compared. A second 0.1-1 GHz amplifier with 21±1 dB is designed in simulation environment with five channels. This five channel amplifier is fabricated and measured results are compared with the simulated ones. A 1-6 GHz three channel amplifier is also designed with a gain of 10.5±0.5 dB. Application of the proposed topology to three different designs shows promising results for future amplifier designs.
