Telewave TPCP-4544 UHF Bandpass Preselectors are specially designedfor use with master receive systems, to ensure rejection of externalnoise sources. These bandpass preselectors provide optimum receiverdesense protection when installed between the receiver multicouplerand the antenna. Their high power capability also allows these unitsto be used as sideband filters on the outputs of transmitters ortransmitter combiners. Bandpass preselectors reject all signalsoutside a selected pass window, and are often preferred at congestedsites.
These bandpass filters consist of 4 series-connected cavities, and are available in a wide range of pass bandwidths. Each model features "sharp-skirt" selectivity with minimum insertion loss. For optimum performance, these bandpass filters are custom tailored tomeet individual requirements. Multiple-window configurations can beprovided when more than one pass band is required. Heavy dutymaterials are used throughout the bandpass filters to insure topperformance and long life, and RG-214 Mil-Spec cable is used forinterconnections. Temperature stability is maintained from -30 to+70°C by the use of temperature compensators, and threaded invar rod. Tuners are silver plated and sliding contacts are made with beryllium copper fingerstock. All models are 19" rack-mountable, and come with N Female connectors.
