Q How to control the amplifier's on/off status?
A It uses CMOS 3.3V level control:RX(LNA)switch is enabled at high level and disabled at low level;TX(PA)switch is enabled at high level and disabled at low level.

Q How to address overheating during long-term operation?
A 1.Ensure adequate ventilation and avoid stacked installations blocking heat dissipation.
2.Clean dust from heat sinks regularly.
3.Contact technical support if overheating persists.
-
Q What to do if there is no output or reduced power?
A 1.Check 5V power supply and ensure current ≤4A.
2.Verify input signal and connector integrity.
3.Check load VSWR≤1.8:1 to avoid triggering protection mechanisms.
-
Q How to correctly connect the IPEX connectors?
A 1.Confirm band and port matching to avoid reverse connection.
2.Insert gently to prevent connector damage.
3.Verify firm contact after connection.

Q Are there any requirements for power-on/off sequence?
A Yes.Power-on:Connect 5V power first,then input control signals.Power-off:Disconnect control signals first,then cut power to avoid instantaneous current surges damaging the module.
