FM Bandpass Cavities - NicomUsa, Inc

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.

Las cavidades de la serie FBP son doble cavidades en cuarto de onda de alto "Q", diseñadas para reducir la intermodulación entre varias frecuencias y eliminar emisiones espureas del transmisor en función. Vienen instaladas entro el amplificador final y la antena y sintonizadas en la fábrica en la frecuencia usada. Son también aptas de ser acopladas en modo de obtener diplexores para varias potencias.
