Product Q&A

Q:What should I check if the output power of the power amplifier is lower than expected during testing?

Troubleshoot step by step: a. Check input signal strength. b. Verify ALC software settings. c. Inspect rear-end components like cables and connectors for excessive loss. d. Test the amplifier independently to confirm hardware faults.

Q:What are the possible causes if the power amplifier gain fails to meet expectations, and how to solve them?

Check software attenuation settings and reduce or disable ATT. Calibrate the test system to ensure component loss is within range. Test the amplifier independently; if it still fails, it may be a hardware fault requiring professional maintenance.

Q:How to accurately locate the problem if the software or instrument shows a high VSWR of the power amplifier?

If software detects high VSWR, replace rear-end components one by one. If an instrument detects it, calibrate the test system first. If issues persist after replacing components and calibrating, it is likely a hardware fault requiring professional maintenance.

Q:What is the operating voltage and current for this amplifier?

The operating voltage is 48V and the operating current is less than or equal to 3.5A.

Q:What are the mechanical dimensions and connector types?

The dimensions are 150*100*23 mm. It has 4 connectors: PA IN is an MCX connector, and the rest are SMA connectors.
