Combining circuit for Class-E RF power amplifiers

摘要: A combining circuit for Class-E RF power amplifiers includes a transformer each amplifier to be combined, the respective secondaries of transformers being connected in series load system. Each further has tertiary winding, with one end first common node, and other second node via an inductance. switchable reactive network is event that removed from circuit, such as due failure thereof, primary terminating impedance thereto will become high impedance, by appropriate switching network, combination remaining components, matching necessary maintain optimum operation achieved, benign VSWR presented amplifiers.
