Abstract: A solid state power amplifier uses a Doherty power amplifier that can be implemented as a monolithic microwave integrated circuit. By adjusting the DC bias of the amplifying stages in each branch of the Doherty amplifier, the output power, linearity, and DC power can be adjusted to provide a specified output, where the specification for the output can include the maintaining of desired DC power and linearity. The Doherty power amplifier can be used in a satellite payload or other application utilizing solid state power amplifiers, while providing the proper amount of RF output power and DC power. A single amplifier can have its bias levels adjusted for different output levels, helping to minimize the number of designs that are required for a given satellite payload, reducing the variety of parts in a satellite payload.

Abstract: A recyclable, laminated polyolefin-based film structure comprises two or more film plies laminated to each other. Each of the laminated film plies comprises one or more polyolefin-based films. The film structure has an energy-cured coating layer disposed on the outermost outward facing surface of the film structure and a printed ink layer on an interior surface of one of the polyolefin-based polyolefin layers. In certain embodiments, the outermost surface of the laminated polyolefin-based film structure has a melting temperature which is at least 100 degrees Celsius, and more preferably 180 degrees Celsius, higher than a melting temperature of the innermost surface of the laminated polyolefin-based film structure.

The field line electrically connects a first and a second input terminal, and is configured to generate a magnetic field based on an input to at least one of the first and the second input terminal. The input is based on a first analog input to the circuit. Each MTJ is electrically connected to a first and a second output terminal, and is configured such that an output of at least one of the first and the second output terminal varies in response to a combined resistance of the MTJs. The resistance of the MTJs varies based on the magnetic field. The circuit is configured to mix the first analog input and a second analog input to generate an analog output based on the output of the second output terminal.

Each of the four RF signal ports includes a waveguide and a reactive element extending into the waveguide. A termination port is electromagnetically coupled to the four RF signal ports and is substantially perpendicular to a geometric plane containing the four RF signal ports. The termination port is substantially coaxial with the fifth RF signal port.
