Although a primary building block for duplexers, multicouplers and preselectors, these cavities filters can be used individually or cascaded together to prevent interference or system clean up. Our cavity filter product line consists of four model types.
All types of RF filters listed below may be cascaded to achieve an arithmetic sum of individual filter attenuation. Up to 6 dB of additional attenuation can be achieved when the proper length of cable is used to interconnect the cavities.
TX RX Triplexers allow the combining of voice TX and RX channels onto a single antenna along with the simplex data only channel. This eliminates the need for a separate data channel antenna and feedline.
