Designed to block the broadcast AM band between 500 kHz - 1.7 MHz with over 50 dB of attenuation. The 3 dB roll-off point is between 2.5 - 2.6 MHz. Works great with any HF receiver or the direct sampling mode on our V3 dongles. This is a high pass filter and not a notch, so VLF will not work.

  • SMA coupler included
  • Low insertion loss
  • Size 2.8 x 2.8 x 1.3cm

The broadcast AM band exists at around 525 kHz to 1.705 MHz. These signals are usually local, and if you live close to a transmitter they can sometimes be extremely strong. Broadcast AM signals that are too strong can overload your SDR or radio, causing poor reception in other HF bands too. The filter also helps attenuate any other strong VLF/LF/MW interference.

Please note: Designed for receive use only. No DC pass-through.
