Important Reminder:
1. Ensure Proper Grounding – Before using this RF power amplifier module, all connected instruments and devices must share a common ground to eliminate potential differences. Connect all components with RF cables and ensure a proper load is connected before powering on. Operating without a load is strictly prohibited, especially for power amplifiers.
2. Use a Proper Antenna – If using an antenna as the load, it must be a properly matched antenna within the working frequency range (with a Voltage Standing Wave Ratio (VSWR) below 2.0). Do not use improper antennas, such as telescopic antennas, copper wire antennas, or extremely cheap antennas, as they have undefined impedance and may cause performance issues or damage.
3. Use a Linear Power Supply – Whenever possible, use a linear power supply, especially when using low-noise amplifiers. Switching power supplies generate significant noise, which can interfere with the amplifier circuit. Avoid using switching power supplies—instead, opt for linear power supplies or batteries for best performance.
