Reliability & Troubleshooting

RF PA Efficiency affects heat, current stress, protection logs, burn-in evidence, and long-term reliability in airport C-UAS cabinets.

RF PA datasheet efficiency can look comparable at 45%. See which test conditions, power definitions, and evidence must match before supplier approval.

Frequency-specific VSWR can trigger at one critical frequency even when other points pass. See why replacing the PA may be wrong—and what evidence proves the cause.

RF PA output drop does not always mean amplifier failure. Check actual Pin, path correction, mismatch, voltage, heat, and protection before replacing the PA.

GaN device quality cannot be proven by branding or one cold test. One hidden lot change or untraceable substitution can put the entire RF PA batch on Hold.

Learn how to prevent water ingress at outdoor RF PA connectors, identify entry paths, separate moisture faults from broader VSWR problems, decide when damaged hardware must be replaced, and define the post-repair RF evidence needed before the resealed connection returns to service.
