Abstract :
This paper describes the design and development of an 11 GHz amplifier, suitable for FDM signals and using a divider-ampllfier-multiplier chain. The overall power amplifier in the 10.7-11.7 GHz bandwidth provides a 32 dB gain, a typical 5.7% efficiency and a 2.5 W power output with expected reliability exceeding 200,000 hours. This amplifier not only has better performances than the well-known Impatt solution, but it is also competitive with FET amplifiers now available on the market.
