1 x RF Amplifier

Note:
1. Before use, all instruments and equipment should be grounded together (without any potential difference), and then connected with RF cables. The load must be connected and it is strictly prohibited to use them without load, especially for power amplifiers.
2. It is necessary to use a "legitimate" antenna, especially when using the antenna as a load, to ensure that the impedance of the antenna matches within the operating frequency (generally requiring a voltage standing wave ratio of less than 2.0). It is strictly prohibited to use "illegitimate" antennas, such as rod antennas, copper wire antennas, and cheap antennas, which have no definite impedance.
3. Use linear power supplies as much as possible, especially when using low-noise amplifiers, be sure to use linear power supplies or batteries. Switching power supplies themselves have a lot of noise, which can enter the amplification circuit. Do not use switching power supplies.
