Reliability is further enhanced by built-in diagnostic features. The amplifier provides real-time current reporting, where the chip translates draw values into a 0-5V analog voltage, enabling precise power consumption tracking. Temperature monitoring uses a linear voltage output scaled at 10 mV per °C, with 500 mV referenced at 25°C. This allows operators to detect thermal drift and trigger over-temperature alarms before performance degradation occurs. Together with its low VSWR tolerance, these features ensure the amplifier operates safely even under fault conditions such as antenna mismatch.
