Abstract
This concise paper presents the realization of a 90°constant phase shifter in the VHF band, which is entirely different from the conventional method for the realization of constant phase shifters in the audio frequency range. The construction of the 90° constant phase shifter is simple and can be easily realized by using a transmission line, and the lumped constant elements, R, L, C. Experimental verification is included.
