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 frequency filters
Lowpass filters are mainly designed for "packetizing" programs in CATV networks. They have been designed to limit the bandwidth required for compulsory broadcasts and block commercial channels. It can also be used for other purposes where such filtration is required.
high-pass frequency filters
High-pass filters are mainly used to "packetizing" programs in CATV networks by cutting out the entire lower range of the TVK, specified band. The lower band is also cut to reduce interference - eg from non-multimedia users or ingress filters.
frequency-band pass filters
Frequency-band pass filters allow you to isolate a suite of commercial programs from the commercial band. They can also cut back the bandwidth of non-multimedia subscribers, limiting interference in this channel to the TVK network.
frequency-band stop filters
Frequency-band stop filters are designed to limit the transmission bandwidth in certain areas of the TVK network and, for example, allow selected users to extract data bandwidth when using the Internet provided by the CATV network.
frequency multi-band filters
Multi-band filters are used in situations where signal filtering needs to be more complex. This is especially true when delivering multimedia services together with a basic social package, or where the bandwidth is split into blocks of channels available under one package or when additional services are provided.
frequency converters
Frequency converters usually produced "on request" - according to individual customer requirements. Typically, two-way (diplexers) or three-way (triplexers) and, depending on needs, they are made in various housing.frequency mast crossovers
frequency mast crossovers are used in terrestrial TV installations for combining signals from different transmitters into one common signal supplied to the receiver with one cable
attenuators
The offer includes regular and permanent attenuators. Regular for smooth signal level adjustment. Permanent attenuators manufactured as wideband silencers or as back-channel attenuators. These attenuators are designed to correct the signal level by a set value.
cable equalizers
The cable equalizers makes it possible to improve the frequency response of the system by reducing the characteristics of the coaxial cable. The equalizer's characteristics are linear and its attenuation decreases with frequency.
isolators
The isolator 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. Isolation is complete, ie both signal path and mass are separated.
power crossovers, power supply
The most common way to use the antenna power supply to amplifiers or antenna preamplifiers is to use a power crossover or power separator.
splitters
Splitters operating in the band up to 1000 MHz and in the satellite band up to 2400 MHz. They are characterized by a large isolation between the outputs and a good fit. Due to the type of housing, two types of splitters are offered: with horizontal outputs - horizontal and vertical - vertical.
taps - multitaps
Splitters operating in the band up to 1000 MHz and in the satellite band up to 2400 MHz. They are characterized by a large isolation between the outputs and a good fit. Due to the type of housing, two types of splitters are offered: with horizontal outputs - horizontal and vertical - vertical.
covers
Cover used in various in different types, series and designs outlets.
