Booster The PRF Booster/520 is a booster amplifier designed specifically for radio frequency (RF) applications. It is designed to provide an additional boost to an existing radio frequency signal, with a gain of up to 20 dB. This allows for greater range, improved performance, and increased reliability for RF applications. The booster amplifier can be used for boosting and amplifying weak or low power signals, as well as for increasing the overall signal strength. It is suitable for both analog and digital applications. The Booster/520 can also be used to improve antenna performance by improving the gain and by reducing the VSWR (Voltage Standing Wave Ratio).
