S-band amplifier module for solid state transmitter

The author describes the realization, performance, and application of an amplifier module that can be used to build high-power amplifiers in solid-state radar transmitters (SSTs). This module optimizes and resolves many critical aspects of the SST application, such as high power output, efficiency, thermal and dissipation effects, electrical performances, reliability, and low production costs. A tradeoff among all these aspects has been carried out to obtain the best solution. A large number of identical modules are connected in parallel to reach the overall final power of the transmitter; therefore, as the cost of S-band transistors decreases and the effective cost of the manufacturing techniques evolves, the SST becomes even more competitive than the tube transmitter.<>
