✈ Some Design Notes



1
Propagation Speed Factor takes into account, that waves travel much faster in air than on pcb. The result is somehow a mixture.
2
The design is based on Silicon Labs AN639.
3
The Matching Capacitor is directly at the BNC (output). Introducing long coaxial cables (100 pF / m) may ruin your day. Use a Preamplifier instead.
