300-330MHz 315Mhz 8W RF Puissance Carte Ampli High Fréquence Ampli de Puissance Module Numérique Puissance Amplificado

Entrée power: 20 23dBm (0.1 0.2W), it can work below 0.1W, the sortie power will increase with the increase of entrée power, and finally reach the maximum power point.
Working voltage: 6-8.4V (typical lithium batterie supply voltage)
Working current: 1.6A (Max)
Entrée Impedance: 50 ohms
Sortie Impedance: 50 ohms
Entrée and sortie terminal: SMA-k female (external thread intérieur hole)
Operating frequency: 300-330MHz
Maximum sortie power (P1dB):
8W (39dBm)@8V 1.56A Efficiency 65%
Notice:
1. Since it is in the UHF frequency band, there are certain requirements for the entrée and sortie cables, and the entrée and sortie are required to be coaxial cables with a characteristic impedance of 50 ohms. If it is connected with ordinary wires, it may not work normally, and there may be strange phenomena such as low sortie power and self-excitation.
2. Due to the high sortie power, do not connect the antenna directly to the sortie port of the power amplifier
Please use a 50 ohm coaxial câble of no less than 2 meters to connect to the antenna to prevent the strong signal from interfering with the normal operation of the power amplifier
3. The power amplifier sortie must be connected to a pure resistive load of 50 ohms. The antenna requires that the standing wave is not greater than 1.5 to ensure the transmission distance and the safety of the power amplifier
4. This power amplifier is a one-way power amplifier, which can only work in one direction, and cannot be used on devices that need to receive signals such as two-way data transmission or walkie-talkies.
