IFBP-1IF Buffer for Panadapter with RF Notch 88-108MHz, Universal

The present circuit was born from an intuition of some American radio amateurs. Many have replicated the circuit we present to you in different ways, perhaps the same engineers from Clifton Laboratories, they in turn adapted and reworked the project which they then published in the past years.

For years, their IF buffers have no longer been available to connect a generic, but also branded, DONLGE SDR to our beloved radios which, despite having a few decades behind them, continue to transmit and motion and for this reason they would like to be able to rejuvenate them in some way .

Many projects were created for this purpose but this one we present to you is one of a kind, probably unique.

In addition to the well-known electrical characteristics of the DEVICE used, ANALOG DEVICE AD8007, it was decided to implement and appropriately adapt a notch filter to eliminate the commercial FM band which, as many will know, is the Achilles' heel of mid-range SDR receivers, perhaps even high end.

Here, in just 3.5cm x 3.5cm, the RF NOTCH BUFFER was created for all radios.

  • Characteristic input impedance > 20kOHM;
  • Output impedance stabilized at 50OHM;
  • Customized gain based on the type of radio in which it is installed (ask when ordering)
  • Equipped with an IPX connector leading to an SMA connector for easy connection of your SDR stick.

Minimum guaranteed features:

  • Reverse isolation >100dB at 30MHz;
  • Gain > 6dB
  • IP3 > +35dB
  • Stop Band FM >60dB
  • Power supply 8-14v (R)
