Sdr hardware front end shield to be used on top of the teensy audio board

NXP Semiconductors
30V 6mA to 15mA, N-Channel Silicon Junction Field-Effect Transistors (FET)
The BF545B is an uncategorised made by NXP Semiconductors in a SOT23-3 package with 3 pins. 30V 6mA to 15mA, N-Channel Silicon Junction Field-Effect Transistors (FET).
PCBKit's library has its KiCad symbol (Transistor_FET:BF545B, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23-3, from KiCad's library), ready for a KiCad board. 2 open-source boards in 2 repositories on GitHub use it.
