RFB-1143 is a high power, four-output RF power amplifier design that delivers up to 50 watts of peak power output across four outputs. It is built with state-of-the-art components, incuding a power divider, preamp, amplifier stages and adjustable output power controllers. Its four outputs are combined to form two separate two-channel amplifiers, allowing each channel to be independently controlled. The RFB-1143 is designed to amplify signals used in radio frequency (RF) communication systems and can operate in a wide range of frequencies between 50MHz and 500MHz. Its small size and high performance make it the ideal choice for applications such as broadcast, point-to-point microwave links, and distributed antenna systems.
