Abstract
The present invention provides a compact slotline balun implemented on a 10-mil thick printed circuit card. The balun utilizes a transition region configuration of a six-port network to achieve a good impedance match and low insertion loss across a wide operating band. The balun is typically manufactured using standard printed circuit techniques which yield a thin, flexible, dimensionally stable device.
