746-869 MHz, Preselectors and Post Selector Filters

Bird Technologies has designed application-specific multi-cavity filter products for use in limiting the bandwidth in front of a multiple-receiver system (Preselector) or after a multiple-transmitter system (Post Selector). Size and complexity range from a model built from three helically-loaded 1.3-inch rectangular resonators for relatively low-selectivity receive-only applications, where 2 dB of loss can be tolerated, to four 6.625-inch cavities that can handle 400 watts with high selectivity and loss of 1 dB or less.
