Set of four Single Pole Double Throw (SPDT) RF Switches with build in 50 Ohm Load for KerberosSDRDesigned by Lakeshore Labs in United States of America
Update 27 Feb 2022: I've taken a break from making these for a while, however due to some recent demand I will be building a limited run of these over the next couple weeks. Building the jumpers is t…Read More…
These switches use the Mini-Circuits HSWA2-30DR+ rated from DC to 3 GHz. Each switch uses a 3.3V control signal from two GPIO (typically from a Raspberry Pi) to select between antenna port 1, antenna port 2, or an internal 50 ohm load.
This set is intended to be used to automate the Kerberos SDR calibration procedure. It eliminates the need to manually disconnect the antennas for the calibration process. The internal 50 ohm load makes the second antenna port available for a dual band array.
Hardware setup instructions: https://github.com/ckoval7/kerberossdr/wiki/gpio_rf_switches
The example code available on GitHub adds an "AutoCal" check box to the KerberosSDR GUI and web interface. With this box checked, updating the receiver parameters will turn off DOA, set your FIR taps to 0, decimation to 1, and run the sample sync and phase correction. Upon completion of the calibration your FIR taps and decimation are restored to their previous state. Re-enabling DOA is a manual step.
