Power Class 3

Thermal Impact

Higher power outputs require more efficient heat sinks to prevent localized hotspots on the printed circuit board. Since power class 3 modules generate moderate heat during continuous transmission, engineers must design thermal paths that route energy away from the transceiver. This design protects nearby components from heat damage.

Supply Stability

Sudden current spikes can cause voltage drops on the power rail if the decaps are too small. When operating in power class 3 mode, the module draws heavy current from the power supply during active bursts. This requires bulk capacitors placed close to the module pins.

Compliance Audit

RF laboratories test the maximum output across all supported frequency bands during the certification process. To pass the test, the module must maintain its power class 3 rating within tight tolerance limits.
