Attention:
* Before using this RF amplifier module, ensure that all instruments and equipment share a common ground (i.e., no potential difference exists between them). Then connect the devices using RF cables, and always connect a load. Operating without a load is strictly prohibited, especially for power amplifiers.
* Make sure to use a proper antenna. When using an antenna as a load, it is crucial to ensure impedance matching at the operating frequency (usually requiring a Voltage Standing Wave Ratio (VSWR) of less than 2.0). Do not use antennas such as telescopic antennas, copper wire antennas, or extremely cheap antennas, as these do not have a defined impedance.
* It is recommended to use a linear power supply, especially when using low-noise amplifiers. A switching power supply generates significant noise, which can couple into the amplifier circuit. Therefore, do not use switching power supplies; use a linear power supply or batteries instead.
* Batteries are not included in the package.
