The DCB 2150 is designed to permit independent Power Supply Operation for LNAs, LNBs, Downconverters and Line Amplifiers by providing a method for breaking the DC continuity and re-inserting DC power. In addition, the RF performance is optimized over the desired 500 MHz bandwidth between 270 - 2150 MHz. The DCB 2150 performs this function for a 75Ω Type F cable system.
