Abstract

There is a strong tendency to use several stages of high frequency amplification in wireless circuits, without paying proper attention to the design of each stage to obtain maximum amplification.
The present paper deals with the design of high frequency transformers to obtain the maximum possible amplification. The cases dealt with include, (i) tuned secondary with untuned primary, (ii) tuned primary with untuned secondary, (iii) primary and secondary tuned to the same frequency. The first of these arrangements is shown to offer advantages over the others.
By proper design, the amplification of a valve and its transformer can be made nearly maximum over the tuning range of the set. The variation of amplification over the band of broadcast wave lengths can be made less than 8 per cent from the maximum at each wave length.
