Aspects and embodiments relate to cavity resonator assemblies and filters formed from those cavity resonator assemblies. A first aspect provides a resonator assembly comprising: a conductive resonator cavity, a primary resonant member, an auxiliary resonant member and a signal feed. The primary resonant member is located within the conductive resonator cavity and arranged to receive a signal from the signal feed and configured to resonate within the cavity at a primary fundamental frequency. The auxiliary resonant member is located within the conductive resonator cavity, arranged to receive a signal from the signal feed and configured to resonate within the cavity at an auxiliary fundamental frequency and configured to impede coupling of a signal from the signal feed to the primary resonant member at the auxiliary fundamental frequency. Arrangements described may allow for independent control of spurious frequencies in resonator or filter output. |
