| May 14, 2022 at 21:27 | comment | added | Yousif Alniemi | Good question with the DC path! I left the cathode floating. A falstad simulation tells me that I should see a big difference with a 1K resistor to ground. Let me try that, and using 100 ohm resistors instead of 1k- I have also not looked into biasing the diode, good idea! | |
| May 14, 2022 at 21:17 | comment | added | Kevin White | The 1k injection resistors seem high for 100MHz. Is there a DC path to ground for the diode? Have you tried adding some forward DC bias for the diode? | |
