Abstract
The feasibility of using high-efficiency IMPATT diodes in the output stage of a high-power amplifier for 11 GHz digital radio relay systems has been proved with a circuit having a gain of 6dB and an output power of 8.4 W. The circuit used is a troughline version of the `Rucker¿ combining circuit and contains two diodes in specially designed packages. Error-rate measurements show that negligible degradation is introduced by the amplifier, which can now be seriously considered as a replacement for the travelling-wave tube amplifier.
