Classification by function
This website presents in addition to the title products - FILTERS AND FREQUENCY CONVERTERS, also attenuators, equalizers and insulators manufactured by PTH MATT.
Filters and switches have been produced for more than twenty years, usually for individual orders, and hence their range of products is very rich, both in terms of construction and functionality, of the transferred bands.. That is why it is often the case that an interesting filter is already developed and its production is a matter of days.
Low pass + band pass filters in tubular housing
Filters RFDP series are designed to limit the transmission bandwidth for Internet-connected customers and limited access to other services. In this series are produced two basic versions of filters - no social package (former RFK symbol) and Internet access and social package (d. RFS symbol). Both versions now have the same designation, and they differ in the specified frequencies of the social, downstream or back channel spectrum.
INPUT: 75Ω asymmetrical impedance male connector "F"
OUTPUT: 75Ω asymmetrical impedance female connector "F"
CONSTRUCTION: galvanically ZnAl alloyed Zn-alloy connection, casing - aluminum tube.
DIMENSIONS: diameter - 20mm, total length depending on the design.
Multipath filters in tubular housing
Multi-band filters RFDPG pass selected lower and upper network bands and selected middle band.
INPUT: 75Ω asymmetrical impedance, male connector "F"
OUTPUT: 75Ω asymmetrical impedance, female connector "F"
CONSTRUCTION: galvanically ZnAl alloyed Zn-alloy connection, casing - aluminum tube.
DIMENSIONS: diameter - 20 mm, total length dependent on specific filter parameters (eg 85 mm RFDPG sample length), the length of the angular filters is 18 mm higher than the straight filters.
