Fixed Diplexer Worksheet

Coleman Microwave Company Diplexers consist of two bandpass filters sharing a common port. Signals applied to the common port are separated in accordance with the passband frequency of each filter network. Signals applied to either non-common port are isolated from the other non-common port and are combined at the common port. The passband of the individual filters may be contiguous or separated by overlapping stopbands.
