Abstract :
An MMIC active phase shifter using a variable resonant circuit is described. Phase can be changed with a constant amplitude by varying the resonant circuit´s reactance. More than 100/spl deg/ phase shift and -4/spl plusmn/1-dB insertion loss was obtained from 2.2 GHz to 2.8 GHz. The chip size is less than 1.0 mm/sup 2/.
