Publication number: 20190260367Abstract: In a portable radio transceiver, a power amplifier system includes a saturation detector that detects power amplifier saturation in response to duty cycle of the amplifier transistor collector voltage waveform. The saturation detection output signal can be used by a power control circuit to back off or reduce the amplification level of the power amplifier to avoid power amplifier control loop saturation.Type: ApplicationFiled: January 24, 2019Publication date: August 22, 2019Inventors: Paul Raymond Andrys, Michael Lynn Gerard, Terrence John Shie

Patent number: 8362840Abstract: Apparatus and methods for biasing a power amplifier are provided. In one embodiment, a packaged circuit includes a power amplifier, a bond wire electrically connected between a system voltage source and a supply input of the power amplifier, a current source, a reference resistor electrically connected between the system voltage source and the current source, and a comparator. The comparator is configured to compare a sense voltage that is based on a voltage across the bond wire to a reference voltage that is based on a voltage across the reference resistor. The comparator is configured to generate a saturation control signal for clamping a bias current of the power amplifier when the sense voltage exceeds the reference voltage.Type: GrantFiled: March 19, 2012Date of Patent: January 29, 2013Assignee: Skyworks Solutions, Inc.Inventors: Paul Raymond Andrys, David Steven Ripley, Terrence John Shie

Patent number: 7729674Abstract: A multi-band communication device with a front end antenna switch module and shared bias circuit is disclosed. Control inputs determine signal routing and amplifier biasing in response to the communication device's mode or band of operation. A received signal is routed to an active path, which corresponds to the band of the received signal. A received signal is selectively switched to one or more switch outputs, which connect to one or more filters matched to the band of the received signal. After filtering, the signal is directly provided to an active amplifier. An amplifier is activated by a bias signal received from a shared bias circuit. The shared bias circuit generates a bias signal which is selectively switched to an amplifier associated with an active path.Type: GrantFiled: January 9, 2007Date of Patent: June 1, 2010Assignee: Skyworks Solutions, Inc.Inventors: Terrence John Shie, Russell David Wyse, Jinhua Zhong
