Patent number: 9559745Abstract: Antenna tuning switch circuitry includes an input port, a shunt switch, control circuitry, and an integrated ground. The shunt switch is coupled between the input port and the integrated ground. The control circuitry includes a control signal input port, a switch driver output port coupled to the shunt switch, and a ground connection port coupled to the integrated ground. The shunt switches, the RF input ports, the control circuitry, and the integrated ground are monolithically integrated on a single semiconductor die. The antenna tuning switch circuitry is adapted to selectively couple the input port to the integrated ground in order to alter one or more operating parameters of an attached antenna. By monolithically integrating the shunt switch together with the control circuitry and the integrated ground, the ON state impedance and the parasitic OFF state impedance of the antenna tuning switch circuitry can be significantly improved.Type: GrantFiled: February 4, 2014Date of Patent: January 31, 2017Assignee: Qorvo US, Inc.Inventors: Jeppe Korshøj Bendixen, Daniel Charles Kerr, Christian Rye Iversen

Patent number: 9531412Abstract: Various embodiments provide for systems and methods for increased linear output power of a transmitter. An exemplary wireless communications system for transmitting an input signal comprises a predistorter module, a GaN power amplifier, a coupler, and an antenna. The predistorter module is configured to detect existing distortion by comparing the input signal to a feedback signal and generate a correction signal. The predistorter may adaptively adjust its operation to minimize the existing distortion due to GaN power amplifier nonlinear characteristics. The result is that the GaN power amplifier may send a power signal of improved linearity to the antenna. The coupler is configured to sample the amplified signal from the GaN power amplifier to generate the feedback signal. The antenna is configured to transmit the amplified signal.Type: GrantFiled: May 5, 2015Date of Patent: December 27, 2016Assignee: Aviat U.S., Inc.Inventors: Jayesh Nath, Ying Shen, Frank Matsumoto, Youming Qin, David C.
