Overview: The cavities of the FBP series are double cavities in high "Q" quarter wave designed to reduce intermodulation among various frequencies and to eliminate spurious emissions from the transmitting unit. They are installed between the final amplifier and antenna and tuned at the factory on the working frequency. They are also suited for coupling in order to obtain diplexers for various power levels.
