You can try other filters setup by calculating the components of each band pass filter.

Two Arduino pins are used to select the right filter depending on frequency. It shows a set of four band pass filters (T section bandpass filter setup). The schematic below uses two FST3253 or two SN74CBT3253D device switches to select one of four bandpass filters.

The two videos below were made using an Arduino Pro Mini 3.3V (8MHz) as the controller. The videos below show an example of the Auto bandpass filter working. Jim Regan, W0CHL, did a great job on auto bandpass filter. The Arduino sketch must have a band table with the appropriate filter information for the band. The main idea of this project is to allow the same Arduino that controls a receiver based on the SI473X, AKC6955, KT0915 or BK108X devices select also the correct bandpass filter depending on the selected reception band. The RF input and output of the original filter has been modified to be easily attached to the SI4735, AKC6955, KT0915 and others DSP based receivers istead the SoftRock Ensemble RX II device. You can see that on Arduino/pu2clr_autobpf_driver folder. I have developed an Arduino Library to control the Auto Band Pass filter device. Originally based on the вЂњSoftrock Ensemble RX II (HF/LF) Auto Band Pass FiltersвЂњ by WB5RVZ, this project uses an Arduino controller instead an ATtiny85.

You will be welcome to the group Si47XX for Radio Experimenters. There is a Facebook group called Si47XX for Radio Experimenters where the purpose is exchanging experiences with projects based on Silicon Labs SI47XX IC family.

#Band pass filter designer code#

This project includes a bandpass filter design based on вЂњSoftrock Ensemble RX II (HF/LF) Auto Band Pass FiltersвЂњ, an Arduino Library to control the filter, documentation and examples.

To do that you will need just two digital Arduino pins. With this project, you can use a set of up to four HF bandpass filters that can be selected by Arduino. It is a HF band pass filter controlled by Arduino.
