Abstract :
A new low-cost design for a planar balanced doubler with ultra-wide bandwidth is presented. This doubler utilizes two types of ultra-wideband transitions: microstrip-to-CPW (coplanar waveguide) and microstrip-to-CPS (coplanar stripline) transitions. The transitions are designed to provide field and impedance matching between adjacent transmission lines. The fabricated doubler provides less than 10 dB conversion loss for output frequencies from 9 GHz to 26 GHz and less than 12 dB conversion loss from 7 GHz to 38 GHz.
