Based on the substrate integrated waveguide (SIW) technology, a new type of varactor-tuned radial power divider has been developed with a single bias supply. The varactors are used as tuning elements and allow for a frequency agile behavior. In addition, bandwidth characteristics have been analysed with group-delay. It has been measured with a single bias supply ranging from 6 V to 12 V that the center frequency of the power divider can be adjusted from 6.6 GHz to 7.2 GHz (600 MHz, 11.5%) while maintaining a low insertion loss (< 1 dB) in the passband.
