FM wireless remote control, FM radio mitter, amateur radio 135-175MHz, 380470MHz walkie-talkie, etc. The low-frequency end input 1mW can output a maximum power of 2.0W, a maximum output of 1.6W at 512MHz, a maximum output of 1.0W at 930MHz, and a maximum output of 1w at 1000MHz. The amplifier is equipped with a heat sink, which can work stably for a long time. The module must first connect the input terminal (RFin) and output terminal (RFout), and finally connect the power supply (DC) to the DC power supply. When the module supplies DC power, be sure to connect the positive and negative poles of the DC correctly. Do not reverse the connection! Otherwise, the module will be damaged! Operating frequency: 1--1000MHz Gain: 35dB (decreases with increasing frequency)<br><br>Input power: 1mW (0dBm) Maximum output: 2.5W (34dBm) Low frequency end (10MHz) 2W (33dBm) Intermediate frequency end (512 MHz ) 1.25W(31dBm) High frequency end(1000 MHz) 1W(30dBm) High frequency end(1000MHz) Working voltage: 12-15V(DC) Note: Although the output power is 2.5W when the power supply is 15V, it cannot work for too long. If the heat sink is too hot, it will stop working to avoid damage! Working current: 300--400mA (determined by output power) RF connector: standard SMA female Colour: Black+Silver Material: Plastic Note: Different batches may have different appearance label printing, which will not affect the use<br><br>Package Contents: 1x RF Power Amplifier<br><br>Only the above package content, other products are not included.
