Design of wide-band R-F transformers utilizing a synthesized equivalent network

Design considerations of wide-band r-f (radio-frequency) transformers operating over a frequency range of 10 to 100 mc (megacycles) are reviewed. The complete basic equivalent circuit representation of transformers must be used in the analysis of the input impedance characteristics. A synthesized equivalent network is used in determining the critical transformer parameters. Experimental data and characteristics of a 25-watt, 20-to 70-megacycle unit are presented.
