In the marketplace, where price and performance requirements are challenging to meet, size has become an extremely important factor for cellular base stations. In current mobile communications bands, air-filled filters, which tend to be bulky, are used in base stations. In this contribution, the alternative use of a dielectric loaded combline filter is proposed in order to reduce the size of filters, and enhance their performance. An eighth-order canonical combline filter is designed with this in mind, for which measured results show improved performance.
