How to Calculate C-UAS System EIRP from PA Output

C-UAS system EIRP is not defined by PA wattage alone. Calculate real EIRP from PA output, RF-path loss, antenna gain, direction, and operating conditions.

How to Judge Usable RF Output Power Before RF PA Selection

Usable RF output power starts with a defined reference plane. Check path loss, minimum PA-port output, heat, DC supply, load, and project margin before RFQ.
