Abstract:A Small size broadband lumped element balun is presented. Analytical expressions for the component values are derived from cascade analysis. The design is a development of the out-of-phase power splitter of second order. This balun maintains the same amplitude balance as the out-of-phase power splitter, but has substantially improved phase balance, and a reduced size. With ideal components the phase balance is 0°, and the amplitude balance less than +/- 0.2dB over more than one octave bandwidth. An experimental demonstrator fabricated by chip components soldered on 0.8 mm PTFE laminate verifies the performance qualitatively. The size of the demonstrator, designed for 3 GHz, is 6*6 mm2.
