RF Amplifiers are the key component in any TV and Radio Transmitter. They use costly transistors and these are cascaded to provide higher powers. So, the main concern of broadcasters is to minimise the failure of these components. The cooling systems, alignments, skills of operating and maintenance personnel are key for minimising the failures and optimal performance of the transmitters. Heat management and stability of the gain of RF amplifiers can be greatly improved by improving cooling systems. This article provides an anatomy of failures of RF Amplifiers and improving their optimal performance through various maintenance strategies.
