DESIGN OF DIVIDED-BAND AMPLIFIERS.
Abstract
The engineering design of UHF multichannel or dividedband amplifiers is discussed. The problems of tube selection and filter design in meeting specified gain and bandwidth requirements are discussed in detail. Several representative types of high-transconductance triodes are considered, as are the circuit restrictions that such tubes impose. Fourth-order Butterworth filters are shown to be entirely adequate to perform band-splitting and recombination, and explicit design formulae are presented for all filter-circuit elements. Performance limitations imposed by currently available tube types are illustrated, and it is shown that the development of tubes with lower output capacitances (even at the expense of larger input capacitances) would permit more efficient amplifier performance.
