Low Pass Filters

Low pass filters attenuate RF energy above a certain cut-off point. A typical use of Low Pass Filter involves suppressing unwanted harmonic (second & above) from a transmitter.

The salient features of the Low Pass Filters are:

  • Upto 18GHz
  • Low Insertion Loss
  • Low V.S.W.R.
  • Broad Stop Band
  • Available in lumped element and suspended substrate form
  • Small Size
  • Note:  You can send your own specfication sheet by fill up the form below (Which is downloadable) and send it to us by fax

    Typical examples of the Low Pass Filters are as in table-1.
