RF Chain, Antenna & EMC

Vehicle RF power measurement fails when teams compare different test points. Define the RF boundary, operating state, load, and acceptance evidence.

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.

Use this RF PA load check to verify antenna path, VSWR, feeder loss, reference point, protection behavior, and stop conditions before full-power integration.

Remote antenna RF PA sizing depends on feeder loss, frequency, power reference plane, and real-load behavior. Learn when more wattage is the wrong fix.

Use this technical review to decide whether an identified dummy-load jumper fits a stated RF PA test. It explains cable-only measurements, power and duty limits, connector and thermal checks, reference planes, and the evidence needed before a controlled high-power run.

An RF PA may pass a 50 Ω dummy-load test yet show a fault after the antenna feed is installed. This guide isolates the feed interface from cable and antenna faults, then defines the measurement plane, mechanical condition, and final hot-state evidence needed for PASS, RETEST, or ROUTE.
