Since 1982 on the market
producer of filters and crossovers frequency
offer / classification by design / tubular housing with a diameter of 20 mm, R-series
Classification by design
PTH MATT has a wide range of passive components, including frequency filters, splitters, faders, equalizers, insulators, frequency converters. Even the most demanding customer should find the right product for his or her needs in the optimal corpus.
Construction of the manufactured components depends on the purpose, required parameters, so also the complexity of the product. Products with only Input and Output (eg filters, insulators, attenuators, equalizers) are usually produced in tubular or cylindrical bodies.
We invite you to read the offer!
Band-pass filters in the tubular housing
RFP filters are designed to limit banding in certain areas of CATV transmission networks.

Band-stop filters in the tubular housing
Bandpass filters RFZ are designed to limit the transmission bandwidth in certain areas of the TVK network and, for example, allow selected receivers to isolate the data bandwidth (or portions of the data channel) when using the Internet provided by the CATV network.
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 depends on the specific filter parameters (the length of the sample RFZ 67-614 is 69 mm), the length of the angular filters is 18 mm higher than the straight filters.
Channel filters in tubular housing
Filters RFC series in the tubular housing are designed to separate the narrow band of a given channel from the TVK band.
INPUT: 75Ω asymmetrical impedance, male connector "F"
OUTPUT: 75Ω asymmetrical impedance, female connector "F"

Graduated silencers of the television band
Graduated silencers are fixed silencers designed to correct the signal level by a set value in the 110 - 862 MHz television band; For the rest of the range, RTT silencers provide minimal attenuation.
INPUT: 75Ω asymmetrical impedance male connector "F",
OUTPUT: 75Ω asymmetrical impedance female connector "F",
CONSTRUCTION: connections - cast ZnAl alloy coated galvanically Zn, aluminum tube housing.
DIMENSIONS: diameter 20mm, length 57mm.
High-pass filters in tubular housing
Highpass filters RFG are designed to limit the transmission bandwidth in certain areas of the CATV network.
INPUT: 75Ω asymmetrical impedance female connector "F"
OUTPUT: 75Ω asymmetrical impedance female connector "F"
CONSTRUCTION: connections - cast ZnAl alloy coated galvanically Zn, aluminum tube housing.
DIMENSIONS: diameter - 20 mm, total length: depending on type - eg RFG 88 57 mm.
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.
Low-pass filters in tubular housing
Lowpass RFD filters are mainly designed to "package" programs on TVK networks.
INPUT: 75Ω asymmetrical impedance, male connector "F"
OUTPUT: 75Ω asymmetrical impedance, female connector "F"
CONSTRUCTION: connections - cast ZnAl alloy coated galvanically Zn, aluminum tube housing.
DIMENSIONS: diameter - 20 mm, total length: RFD 214, 230: 67 mm; RFD 470, 606 - 88mm.
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.
Tube corrector cable
Tube corrector cable allows the system to improve the frequency response of the system by eliminating the characteristics of the coaxial cable.
INPUT: 75Ω asymmetrical impedance male connector "F"
OUTPUT: 75Ω asymmetrical impedance female connector "F"
CONSTRUCTION: connections - cast ZnAl alloy coated galvanically Zn, aluminum tube housing.
DIMENSIONS: diameter 20mm, length - 63mm.
TVK isolator 3 kV
Isolator RMI is designed to isolate the CATV installation from the part of the installation located on the subscriber. It is also used where the mass potential of the CATV installation and the "zero" of the subscriber power supply is different.
INPUT: 75Ω asymmetrical impedance male connector "F"
OUTPUT: 75Ω asymmetrical impedance female connector "F"
CONSTRUCTION: connections - cast ZnAl alloy coated galvanically Zn, aluminum tube housing.
DIMENSIONS: diameter 20mm, length - 57mm.
