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.
Adjustable silence 0 ÷ 20dB
Adjustable silence MTR 20 is designed for smooth adjustment of the signal level.
Input: asymmetrical impedance 75Ω female connector "F"
Output: asymmetrical impedance 75Ω female connector "F"
Construction: ZnAl alloy coated with galvanic Zn.
Dimensions: (with connectors): 48.0 x 38.0 x 17.5 mm.
Constantly return channel silencers
Constantly return channel silencers are designed to correct the signal level by a set value in the 5 - 65 MHz return channel band, while minimizing the rest of the range to the rest.
INPUT: asymmetric impedance 75Ω male connector "F"
OUTPUT: asymmetric impedance 75Ω female connector "F"
CONSTRUCTION: ZnAl alloy coated with galvanic Zn.
DIMENSIONS: (with connectors): 48.0 x 38.0 x 17.5 mm.
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.
Permanently attenuators 5-862 MHz in cylindrical housings
Permanently attenuators WTS (2-4-6-8-10-12) designed to adjust the signal level by a set value in the 5 - 862 MHz band; The rest of the range bring minimal attenuation.
INPUT: 75Ω asymmetrical impedance male connector "F"
OUTPUT: 75Ω asymmetrical impedance female connector "F"
CONSTRUCTION: housing rolled brass alloy coated with Ni plating,
DIMENSIONS: diameter 11mm, length 57mm.
Progressive return channel attenuators 5-65 MHz
Progressive return channel attenuators WTK (2-4-6-8-10-12) are fixed attenuators designed to correct the signal level by a set value in the 5 - 65 MHz return channel band; The rest of the range bring minimal attenuation.
INPUT: 75Ω asymmetrical impedance male connector "F"
OUTPUT: 75Ω asymmetrical impedance female connector "F"
CONSTRUCTION: housing rolled brass alloy coated with Ni plating,
DIMENSIONS: diameter 11mm, length 57mm.
