1. Product Overview
The DIXSG Customzie Band PA Module is a versatile radio frequency power amplifier designed for amateur radio and other applications requiring signal enhancement. Available in various power outputs (10W, 30W, 50W, 100W) and corresponding gain levels (40dBm, 45dBm, 47dBm, 50dBm), these modules are built with robust aluminum shells and feature circulators for reflected power protection in higher wattage models.
2. Safety Precautions
- Always ensure the module is connected to an appropriate antenna or dummy load before applying power. Operating without a load can cause severe damage due to high reflected power and overheating.
- Proper heat dissipation is crucial for stable and long-term operation. Always use a suitable heat sink and, if necessary, a radiator fan for forced cooling.
- Handle the module with care to avoid physical damage to connectors or internal components.
3. Setup and Connection
3.1 Wiring Scheme
The module uses a simple three-wire connection for power and control:
- White wire: Module switching control line. The module activates after power supply is connected and this line is properly managed.
- Red and white wire: Positive power supply (+28V).
- Black wire: Negative power supply (-28V).
3.2 Connector Types
The input and output connectors vary by module power:
- 10W, 30W, 50W Modules: Input and output connectors are SMA Female.
- 100W Module: Input connector is SMA Female, output connector is N Female.
When selecting an antenna, ensure it has the corresponding frequency and a male connector that matches the module's output connector.
3.3 Heat Dissipation
Effective heat dissipation is critical. Apply thermal glue, attach a suitable heat sink, and consider using cooling fans for forced air circulation to maintain stable operating temperatures and prevent damage.
4. Operating Instructions
- Ensure all connections (power, input, output to load/antenna) are secure and correct.
- Verify that the module is connected to an appropriate load or antenna.
- Apply the specified 28V power supply to the red/white (positive) and black (negative) wires.
- Activate the module using the white control line.
- Monitor the module's temperature during operation. If it becomes excessively hot, immediately disconnect power and check heat dissipation measures.
5. Maintenance
Regular maintenance primarily involves ensuring optimal heat dissipation:
- Periodically check the heat sink for dust accumulation and clean as necessary.
- Ensure cooling fans (if installed) are functioning correctly and providing adequate airflow.
- Inspect all wiring for signs of wear or damage.
6. Troubleshooting
- Module not activating: Check power supply connections (+28V, -28V) and ensure the white control line is properly managed.
- Overheating: Immediately disconnect power. Verify that the module is connected to a load/antenna and that heat dissipation measures (heat sink, fans) are sufficient and correctly installed. Operating without a load is a common cause of overheating.
- No output power: Check input signal, power supply, and all connections. Ensure the module is activated.

7.3 Circulators and Protection
30W, 50W, and 100W modules are equipped with circulators, isolators, and duplexers. These components prevent damage to circuit boards from no-load conditions and reflected signals, ensuring safety and reliability by preventing burn-in.
8. User Tips
- Always use a dummy load for testing: Before connecting to an antenna, use a dummy load to test the module's functionality and prevent accidental damage.
- Ensure proper grounding: A stable ground connection is essential for optimal performance and safety.
- Verify connector types: Double-check that all input and output connectors match your cables and antenna to avoid signal loss or damage.
- Monitor power supply: Use a stable and regulated 28V power supply to prevent voltage fluctuations that could affect performance or damage the module.
