Patent number: 10249929Abstract: A multimode directional coupler is provided. In some embodiments, the multimode directional coupler is configured to receive a primary signal and a secondary signal at a first port of a primary waveguide. The primary signal is configured to propagate through the primary waveguide and be outputted at a second port of the primary waveguide. The multimode directional coupler also includes a secondary waveguide configured to couple the secondary signal from the primary waveguide with no coupling of the primary signal into the secondary waveguide. The secondary signal is configured to propagate through the secondary waveguide and be outputted from a port of the secondary waveguide.Type: GrantFiled: January 29, 2016Date of Patent: April 2, 2019Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Rainee N Simons, Edwin G Wintucky

Patent number: 10033083Abstract: One or more embodiments of the present invention describe an apparatus and method to combine unequal powers. The apparatus includes a first input port, a second input port, and a combiner. The first input port is operably connected to a first power amplifier and is configured to receive a first power from the first power amplifier. The second input port is operably connected to a second power amplifier and is configured to receive a second power from the second power amplifier. The combiner is configured to simultaneously receive the first power from the first input port and the second power from the second input port. The combiner is also configured to combine the first power and second power to produce a maximized power. The first power and second power are unequal.Type: GrantFiled: October 14, 2016Date of Patent: July 24, 2018Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Rainee N. Simons, Christine T. Chevalier, Edwin G. Wintucky, Jon C. Freeman

Patent number: 9490899Abstract: An optical tunable transmitter is used to transmit multiple radio frequency bands on a single beam. More specifically, a tunable laser is configured to generate a plurality of optical wavelengths, and an optical tunable transmitter is configured to modulate each of the plurality of optical wavelengths with a corresponding radio frequency band. The optical tunable transmitter is also configured to encode each of the plurality of modulated optical wavelengths onto a single laser beam for transmission of a plurality of radio frequency bands using the single laser beam.Type: GrantFiled: May 2, 2014Date of Patent: November 8, 2016Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Hung Nguyen, Rainee N. Simons, Edwin G. Wintucky, Jon C. Freeman

Patent number: 9041469Abstract: One or more embodiments of the present invention pertain to an all solid-state microwave power module. The module includes a plurality of solid-state amplifiers configured to amplify a signal using a low power stage, a medium power stage, and a high power stage. The module also includes a power conditioner configured to activate a voltage sequencer (e.g., bias controller) when power is received from a power source. The voltage sequencer is configured to sequentially apply voltage to a gate of each amplifier and sequentially apply voltage to a drain of each amplifier.Type: GrantFiled: March 20, 2013Date of Patent: May 26, 2015Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Rainee N.
