NANO-ERF® Series

The NANO-POLE® Extended Range Series of tunable filters was developed to address applications needing an extremely small surface-mount package with low power consumption.  Wide tuning range is accomplished with careful design to minimize size and power consumption.

General Information

The NANO-ERF™ tunable filter requires a +3.3 VCD analog and digital supply.  This supply voltage must be adequately filtered as noise present on this pin will directly influence the RF signal purity.

Digital Interface Information

The digital interface format is SPI serial. All data input pins are data bus capable of 3.3V logic levels.
