433MHz RF Power Amplifier Board Professional 400‑460MHz Extended Range RF Amplifier Module for

Feature: 1. High Efficiency: Power amplifier board can output a maximum of 39.2dBm (8.31W) at 8V 433MHz, current 1.56A, efficiency 66.5percent , ideal for two lithium batteries powered by the best results can be achieved. 2. UHF Band: RF power amplifier board because it is UHF band, so the input and output cables have certain requirements, requiring the input and output are 50 Ohm characteristic impedance of coaxial lines. 3. Coaxial Cable Connection: Please use not less than 2m6.6ft of 50 ohm coaxial cable to connect to the antenna to prevent strong signal interference with the normal operation of the amplifier in close proximity. 4. One Way Power Amplifier: RF power amplifier board for one way power amplifier, can only work in one direction, can not be used in two way digital transmission or walkie talkie and other equipment that needs to receive the signal above. 5. Premium Material: 433MHz RF power amplifier board using premium aluminum alloy and PCB material, rugged, safe and reliable, anti aging, long service life.
