T-section dual-band impedance transformer for frequency-dependent complex impedance loads

A simple and successful design for matching complex impedance loads with different values at two different frequencies is presented. The explicit closed-form equations for the transformer parameters are derived analytically. The validity of the proposed design is verified by a numerical example of designing the input matching network of an amplifier.
