ORDERING PROCEDURE

GLOSSARIES

Please designate following items when ordering

  • Nominal Frequency;
    Nominal value of center frequency.
  • Pass Band Width and Attenuation Band Width;
    The space of frequency whose relative attenuation is equal to the specified value.
  • Attenuation which specifies Pass Band Width or Attenuation Band Width;
    The frequency band whose relative attenuation takes the specified value or more.
  • Ripple;
    The difference between the maximum loss and the minimum loss in the guaranteed pass band.
  • Terminal Impeadance;
    The power source impeadance or load impeadance seen from the filter side.
1. Holder Type

2. Normal Frequency
