Abstract
An RF power amplifier network with a redundant power supply comprising a plurality of RF power amplifiers. Each RF power amplifier includes a power supply unit and an amplifier load. The power supply unit is adapted for receiving a primary input voltage Vin and producing a secondary output voltage Vout, and the power supply unit is further adapted for generating a power supply fail signal upon failure of the power supply unit. The network further includes a supply bus to which is connected each power supply unit of each RF power amplifier, and each amplifier load of each RF power amplifier. A switch associated with each of the power supply units is responsive to the fail signal for disconnecting the power supply unit from the bus in the event of failure of the power supply unit. A second switch is associated with each of the RF power amplifiers for disconnecting an amplifier load from the bus if the current drawn by the amplifier load exceeds a predetermined maximum threshold value or falls below a predetermined minimum threshold value.
