SUMMARY
The forum discussion centers on troubleshooting a malfunctioning assembly of two Gallium Arsenide Field Effect Transistors (GaAs FETs) in a high-frequency (HF) system. Despite correct voltage readings at the drains and sources, the assembly has ceased to function. Participants emphasize the importance of providing a schematic and part numbers for effective diagnosis, suggesting potential issues such as a shorted inductor, open capacitor, or faulty solder joints. The discussion highlights the need for detailed information to avoid guesswork in troubleshooting.
