This chapter describes transmitting tube circuits because tubes still provide the most practical and economical means of achieving the high performance necessary for multichannel (ISB) transmission at power levels above 1 kW (at present). The opening section provides a good discussion of IMD. This chapter will then show how to choose and compute tube-operating conditions. Tank circuit and coupling network requirements will be discussed, and neutralization and stabilization circuits will be shown. Finally, RF feedback circuits will be described as an effective means of improving IMD performance.
