High Power
Waveguide & Coaxial Filters

High Power microwave transmitters radiate an appreciable amount of spurious output power, that is, frequency components other than the carrier frequency and the normal sideband modulation signals. It is necessary to use high power filters at the output of these transmitters that wil pass the carrier and normal modulation signals but suppress the spurious emmissions, and thus, keep them from causing interference in neighboring equipment. Coleman Micowave Company's technical staff has vast and in-depth experience in the design and development of high power filters for radar and communications systems in waveguide and coaxial transmission lines.
