摘要： An embodiment of an amplifier system includes a modifiable signal adjustment device with an RF signal adjustment circuit coupled between first and second nodes. The RF signal adjustment circuit includes an adjustable phase shifter and an adjustable attenuator coupled in series with each other. The device also includes a memory and a controller circuit. The controller circuit retrieves a phase shift value and an attenuation value from the memory. The controller circuit then controls the adjustable phase shifter to apply a phase shift corresponding to the phase shift value to an input RF signal received at the first node, and controls the adjustable attenuator to apply an attenuation corresponding to the attenuation value to the input RF signal. Applying the phase shift and the attenuation results in an output RF signal at the second node.

摘要： The embodiments described herein provide a radio frequency (RF) driver amplifier and method of operation. In general, the driver amplifier facilitates high performance operation in RF devices while being implemented with only n-type transistors. Using only n-type transistors in the driver amplifier can increase the operating bandwidth of the driver amplifier. Furthermore, using only n-type transistors in the driver amplifier can simplify device fabrication. The driver amplifiers and methods described herein can be used in a variety of applications. As one specific example the driver amplifier can be used in a switch-mode power amplifier (SMPA). Such a SMPA can be configured to amplify a time varying signal, such as an RF.

摘要： The embodiments described herein provide inverse class F (class F−1) amplifiers. In general, the inverse class F amplifiers are implemented with a transistor, an output inductance and a transmission line configured to approximate inverse class F voltage and current output waveforms by compensating the effects of the transistor's intrinsic output capacitance for some even harmonic signals while providing a low impedance for some odd harmonic signals. Specifically, the transistor is configured with the output inductance and transmission line to form a parallel LC circuit that resonates at the second harmonic frequency. The parallel LC circuit effectively creates high impedance for the second harmonic signals, thus blocking the capacitive reactance path to ground for those harmonic signals that the intrinsic output capacitance would otherwise provide. This facilitates the operation of the amplifier as an effective, high efficiency, inverse class F amplifier.

摘要： The embodiments described herein provide compensation for mutual inductance in a multi-path device. In one embodiment, a device includes a multi-path integrated device. The multi-path integrated device includes a first output and a second output. The first output is configured to be coupled to a first output lead through a first bonding wire, and the second output is configured to be coupled to a second output lead through a second bonding wire. Due to their proximity, the second bonding wire has a first mutual inductance with the first bonding wire. A first compensation network is coupled to the first output, and a second compensation network is coupled to the second output. The second compensation network is configured to have a second mutual inductance with the first compensation network. The second mutual inductance at least partially cancels the effects of the first mutual inductance.

摘要： An embodiment of an amplifier includes N (N>1) switch-mode power amplifier (SMPA) branches. Each SMPA branch includes two drive signal inputs and one SMPA branch output. A module coupled to the amplifier samples an input RF signal, and produces combinations of drive signals based on the samples. When an SMPA branch receives a first combination of drive signals, it produces an output signal at a first voltage level. Conversely, when the SMPA branch receives a different second combination of drive signals, it produces the output signal at a different second voltage level. Finally, when the SMPA branch receives a different third combination of drive signals, it produces the output signal at a voltage level of substantially zero. A combiner combines the output signals from all of the SMPA branches to produce a combined output signal that may have, at any given time, one of 2*N+1 quantization states.

摘要： An embodiment of a device includes a terminal, an active transistor die electrically coupled to the terminal, a detector configured to sense a signal characteristic on the terminal, and control circuitry electrically coupled to the active transistor die and to the detector, wherein the active transistor die, detector, and control circuitry are coupled to a package. The control circuitry may include a control element and a control device. Based on the signal characteristic, the control circuitry controls which of multiple operating states the device operates. A method for controlling the operating state of the device includes sensing, using the detector, a signal characteristic at the terminal, and determining, using the control device, whether the signal characteristic conforms to a pre-set criteria, and when the signal characteristic does not conform to the pre-set criteria, modifying the state of the control element to alter the operating state of the device.

摘要： A reconfigurable Doherty power amplifier includes a packaged power splitter device, main and peaking amplifiers, and a combiner circuit. The power splitter device includes a power divider, input terminals coupled to first and second ports of the power divider, and output terminals coupled to third and fourth ports of the power divider. One of the input terminals is coupled to an RF signal input terminal, and the other input terminal is terminated. The power divider receives an input RF signal, and produces main and peaking RF signals at the third and fourth ports of the power divider, respectively. The main and peaking amplifiers amplify the main and peaking RF signals, respectively. The combiner circuit includes a summing node and a phase delay element between outputs of the main and peaking amplifiers. An RF signal output terminal is coupled to the summing node.
