Bandpass Filters

Bandpass filters can be supplied in a variety of different technologies, including but not limited to coaxial ceramic, cavity, lumped, helical, waveguide, tubular and microstrip. Chebyshev response filters are available, as well as Bessel, Gaussian, linear phase, Butterworth, elliptical and other transfer function filters.

ISM-Band Bandpass Filter

This TX/RX filter dramatically reduces adjacent and out-of-band interference to the ISM band (902-928 MHz), allowing higher data rates and improved range.

  • High Q, low loss
  • Extremely sharp lowside cutoff limits 800 MHz cellular-band noise and interference
  • Available with SMA adapter board or standalone

Designed for infrastructure ISM-Band users

  • Automated data collection
  • Dedicated monitoring
  • Data links
