AVS Series Miniature Lowpass Video Filters

avs  download the 6 page AVS brochure in Adobe pdf format
       The AVS Series, Miniature Broadcast Quality Filters were designed with Original Equipment Manufacturers in mind. Allen Avionics AVS Series Miniature Lowpass Video FiltersTheir miniature size and superior performance will enhance any analog or digital video product.
       Flat amplitude and group delay, combined with excellent transient response, make the AVS Series Filters especially suitable for digital processing equipment as Pre-Filters before A/D converters and Post-Filters after D/A converters.
       Sin x/x correction is available for Post filtering with no increase in  package size. Wide bandwidths and sharp stopband ratios assure all information will be transmitted to the D/A converter while maximizing attenuation at the Nyquist frequency.
        Six different stopband ratios from 1.25 to 1.75 are available. Sin x/x correction is available for all stopband ratios. The AVS Series Filters are available in Single-In-Line and Dual-In-Line epoxy packages or in metal cases, all for PC board mounting.
Features
  • 6 different stopband ratios
  • Available packages for PC board mounting
    • Single-In-Line
    • Dual-In-Line

K = 2.50 K = 2.50 K = 2.50 K = 2.50 K = 2.50 K = 2.50
