Abstract:
1. A filter assembly, comprising: a block resonator filter comprising a block of dielectric material having a conductive plating; and a means for tuning at least one of three resonant frequencies associated with the block resonator filter; and the tuning means comprising an affected area of the conductive plating having a determined shape for selectable increasing or decreasing the at least one resonant frequency, wherein a circular shape increases the resonant frequency, and a slot decreases the resonant frequency; and a mask filter operably connected to said block resonator filter, wherein a passband of said mask filter is wider than a passband of said block resonator filter; and a low-pass filter operably connected to said block resonator filter, wherein said low-pass filter rejects frequencies greater than the passband of said block resonator filter.
