RF Preselectors and Post Selectors Filters
Preselectors are primarily used to limit the bandwidth in front of a multiple-receiver system and Post Selectors are used to limit the bandwidth after a multiple-transmitter system. 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.
Bird Technologies, TX RX Systems brand, offers a wide variety of standard and custom preselector and post selector filters to meet the requirements of the communication systems that have been and are being designed today.
