With the deployment of ‘micro’ base stations and the co-location of multiple cellular services, the challenge is on to fit more and more equipment into a shrinking amount of space. One component that can occupy a significant fraction of base station volume is the RF bandpass filter, increasingly introduced to control interference and improve quality of service
