  1. We ask you to familiarize yourself with the laws of your country on the use of radio frequencies and the power of transmitters. You can change the output power of the amplifier by changing the power at its input. You can convert dBm to Watts using the on-line calculator at https://www.rapidtables.com/convert/power/dBm_to_Watt.html
  2. A heat sink must be used for the amplifier to work.
  3. As a transceiver, you can use TiTAN/TiTAN-I development board or whatever you like.
  4. To achieve the best result, the power supply of the amplifier must be supplied with a wire with a cross section of at least 0.5 mm2 and a length of no more than 100 mm.
