Filters AG Vorstadt 32 CH, 6304 Zug Switzerland teletronik@teletronik.com www.teletronik.com FILTERS TECHNICAL OVERVIEW Filters in CATV networks are used to perform signal processing functions, more specifically filters intend to remove unwanted signal components and/or enhance wanted ones. Designing a filter for high frequencies (5MHz to 1GHz) is a technical challenge as parasitic components aproach and further more shielding against RF signals is most vital. teletronik filters are produced with SMD parts for reduced signal path and increased reliability and are hand tuned separately to optimum. Our filters use a patent pending shielding inside the filter tube, which outperforms common EMI shielding used in other filters. teletronik has the flexibility to produce any type of filter that suits your needs. If your CATV system requires a special type of filter that is commonly not in production feel free to contact us. Specification may change without notice FILTERS FILTER TYPES Low pass filters Low pass filters pass lower frequencies / channels and reject the higher ones. Low Pass filters are frequently used to filter out signals outside the CATV band or to eliminate a whole range of higher channels. High pass filters High pass filters pass only higher frequencies / channels and reject anything below the cut-off frequency. HPF filters are mostly used to attenuate the CATV return path band (5-54MHz or 5-85MHz). Trap filters Trap filters are used to filter out only a single frequency. There are two types of trap filters: Negative trap filters directly cut out a channel a CATV customer has not subscribed to. Positive trap filters cut out the jamming frequency that is added to the signal from the head-end. Tier trap / Band reject filters Tier trap filters are made up of a number of trap filters. TT filters are used to reject a limited number of CATV channels. Reject band range: 20-150MHz Band reject filters are used to eliminate a wider band of frequencies from the CATV frequency table. Reject band range: 300MHz -500MHz Band pass filters Band pass filters have a frequency response that is the opposite of Band Reject Filters. BP filters pass only one band of frequencies / channels, everything below and above this pass band is rejected. Window filter A window filter contains one band-pass and one low-pass or high-pass filter. The first combination is used for subscribers only interested for CATV internet services while the other type is used by customers wanting only a reduced number of TV channels.
