Abstract
This paper presents a ferrite tunable waveguide filter showing high Qu and high tunability in X-band. A new type of waveguide cavity resonator with an H102 operating mode was proposed for the creation of a low-loss, two-pole filter. The filter results in an insertion loss of 3.6–4.1 dB over the tuning range 8.74–9.63 GHz with a relative bandwidth of 0.92–0.79% and biasing magnetic field 0–600 Oe. This design demonstrates an unloaded quality factor of 380–396 over the tunable frequency range.
