LNB Supply & Control Evaluation Boards
STMicroelectronics LNB Supply and Control Evaluation Boards provide a reference design for powering the LNB (Low Noise Block) supply ICs intended for analog and digital satellite receivers, satellite TV, and satellite PC applications. LNB supply ICs are highly-efficient monolithic linear and switching ICs specifically designed to provide both power and interface signals to the LNB downconverter placed on the antenna dish, via the coaxial cable. The LNB Supply and Control Evaluation Boards implement a DC-DC converter based on the LNBH25L or LNBH29 device used to power the LNB inside dish antennas, which receive satellite TV signals.
