MATV / RF Filters & Traps
- MATV filters & traps are NTSC channel / frequency standard, 75 ohms impedance with F-type female connector
- Customizing is available. Please inquire for other frequency, connector, or impedance standards. Example configuration: PAL / BNC / 50 ohms.
- Production graphs are provided for many filters & traps to illustrate typical frequency response
- To refer to CATV or Broadcast channel or frequency - see NTSC Freq. Chart
BANDPASS
Used to pass a desired TV channel or segment of TV/RF spectrum (from 40 to 860 MHz) and reject out of band frequencies. Adjacent and semi-adjacent models available.
NOTCH TRAPS
Attenuation of signal at specific frequency (4 to 900 MHz). Use to suppress an interfering carrier, and other applications. Models available with multiple notches, indoor and outdoor housing.
- Fixed frequency
- Trap with switch
- Tunable notch
Go to:
BANDSTOP
Band rejection filters with non-adjacent channel selectivity, designed for off-air antenna systems. Use to attenuate specific TV channel or RF signal band. Typical stopband: specify from 15dB to 30dB.
LOWPASS
Designed to pass desired frequencies in lower segment of TV spectrum and reject frequencies in upper segment. Custom specifications available.
HIGHPASS
Designed to pass desired frequencies in upper segment of TV spectrum and reject frequencies in lower segment.
CHANNEL COMBINERS
Combiners consist of individual bandpass filters joined together at common port. Combines multiple single-channel sources into one output, or, separates broadband signal into individual channels: TV & FM
ANTENNA DIPLEXERS
Three port devices consist of a highpass, lowpass joined together at a common port. Combines or isolates two signal bands, e.g., VHF (0-230 MHz), UHF (470-860 MHz)
TV CHANNEL INJECTORS
Injectors consist of a bandpass, bandstop joined together at a common port. Used to network off-air antennas, or combine a single channel with a broadband signal.
