  • The combline filters are designed for minimizing interference from adjacent channels and outside systems. They are available in a wide range of bandwiths and frequency splits. Used in front of a wideband receiver multicoupler, the preselectors narrow the passband to the desired bandwidth. Each filter is temperature-compensated for operation between -40ºC to +60ºC. Each filter has silver-plated loops and tuning rods.

    Our preselectors are available in a wide range of frequency splits, bandwidth and cavity sizes.

    • Temperature  compensation: ensures frequency stability
    • High attenuation: minimizes desense and interference from adjacent systems

    Other preselectors are also available.  They include comblines and our full line of cavity-based preselectors. Sizes range from the very compact 1” helical filter to the very selective 6.625” cavity preselector. Please contact a technical support technician for consultation.
