Abstract
The varactor-tuned miniaturised hairpin tunable filter with a single control voltage is presented. The proposed tunable filter is designed and fabricated with the constant ratio rule in which the capacitances of each stage always maintain a constant ratio without any dependency to miniaturised electrical length. As a result, the filter can be tuned with the reserved equivalent condition using a single control voltage.
