Abstract
A dielectric resonator filter is configured to suppress emissions in an out-of-band frequency portion of an amplified radio frequency (RF) signal prior to transmission of the RF signal by an antenna assembly. The filter includes plural tunable resonant cavities, each of which have a dielectric resonator and are arranged to suppress a magnitude of a frequency component in the out-of-band frequency portion of the RF signal. The amplified RF signal is applied to the plural resonant cavities with a microstrip transmission line. The dielectric resonators are arranged so as to automatically compensate for temperature-induced resonance condition variations.
