Possible Cause
Connector Wiring
Supply Voltage Range
Exceeded
Power Supply Current
Insufficient
Over-Temperature
Protection being
triggered. Amplifier
exceeding
recommended operating
temperature
Improper wiring harness
connections
Improper RF
connections
Excess radio output
power - EVM too high
Solution
Ensure proper connections are made to wiring
harness.
Consult wiring diagram on product's spec sheet
Ensure power supply output is set to acceptable
voltage range.
Consult spec sheet for operating voltage range
Ensure power supply is capable of supplying at least
1.5x the expected current draw of the amplifier. This
is due to the inrush current of the unit as it powers
on
Ensure sufficient heatsinking has been applied to
unit. Add or increase airflow to heatsink
Refer to section 3.1 and verify that the proper
connections have been made between the SC4200
and Triad BDA wiring harnesses
Refer to section 3.2 and verify that the proper RF
connections have been made between the SC4200
and Triad BDA
Reduce radio output power in 0.5 dB steps until data
rate improves.
