Description

Our ceramic combiner uses dielectric resonator technology to offer higher performance than standard RF cavities in a much smaller package. It combines 4 channels in only 7.75” of standard 19” rack space. The resonator allows combining of transmitters at a frequency spacing as close as 150 KHz. Lower insertion loss per channel is another result of the sharper filtering performance. Expandable in individual channel increments.
