Our Bandpasser Singles are single band versions of the filter designs used in our Bandpasser (MBF-100) multi-band filter systems. All filters except 10M are 3-pole Chebyshev bandpass designs. They provide over 40 dB rejection of adjacent bands (excluding WARC) and have low insertion loss (< 0.6 dB). The 10M is a Cauer high-pass design that provides deep notches on the 15M and 20M bands while offering a very low insertion loss (< 0.2 dB). These filters are rated for 100W.

Our top-of-the-line bandpass filters are an elliptical (Cauer) bandpass configuration which provides maximum rejection of adjacent bands (excluding WARC) along with a low insertion loss. Rejection of the next lower band is over 50 dB while rejection of the adjacent band above is typically more than 60 db.  These filters are ideal for multi-band FT-8 operation.  More information on the EF series page.
