Abstract: A circulator-coupler device includes a ferrite element, a resonator over and aligned along an axis with the ferrite element, and a plurality of resonator ports connected to the resonator. The plurality of resonator ports includes first and second resonator ports, and a first portion of a perimeter of the resonator extends between the first and second resonator ports. The circulator further includes a coupler element positioned across a gap from the first portion of the perimeter of the resonator, and a coupler port connected to the coupler element. The device also may include a permanent magnet aligned along the axis with the ferrite element, where the permanent magnet biases the ferrite element and causes a signal conducted through the resonator to have a directionality along a rotational direction that extends from the first resonator port to the second resonator port.

Abstract: Power amplifiers, amplifier systems, and related methods are disclosed herein. In one example embodiment, the amplifier system includes a bias controller that enables fast switching between an on state bias voltage and an off state bias voltage for the power amplifier. The bias controller can transition a low impedance switch to an on state to electrically couple a first electrode of a charge holding capacitor to an input of the power amplifier. The charge holding capacitor can be pre charged with the on state bias voltage to quickly provide the on state bias voltage to the power amplifier. The bias controller can also transition the low impedance switch to an off state to couple the input of the power amplifier to the off state bias voltage.

Abstract: 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.

Abstract: A Doherty amplifier is able to enhance efficiency in low-power and high-power RF communication states by enabling carrier and peaking amplifiers as required, and controlling bias modulation, depending on traffic loading levels in each of a set of consecutive communications timeslots. For example, if, in a low-power state, traffic loading levels do not exceed a relatively lower threshold in a communications timeslot, carrier amplifiers are selectively enabled as needed, peaking amplifiers are not enabled, and carrier amplifier bias levels are kept substantially constant. If, in an intermediate-power state, the lower threshold is exceeded but a relatively higher threshold is not exceeded, all carrier amplifiers are enabled, peaking amplifiers are selectively enabled, and bias levels are kept substantially constant. If, in a high-power state, the higher threshold is exceeded, all carrier and peaking amplifiers can be enabled, and the peaking amplifier bias tracks the RF envelope of the received RF signal.

Abstract: A device includes an amplifier having an input terminal and an output terminal. The input terminal is configured to receive a radio frequency (RF) input signal. The device includes an output network coupled to the output terminal of the power amplifier and a first passively tunable integrated circuit (PTIC) coupled to the output network. The first PTIC includes a direct-current (DC) bias voltage input terminal configured to receive a fixed bias voltage, a control signal input terminal configured to receive a time-varying control signal, wherein the fixed bias voltage in combination with the time-varying control signal sets an operating reference point of the first PTIC, and an input terminal electrically connected to the output terminal of the amplifier, wherein a change in an output voltage signal generated by the power amplifier causes the first PTIC to modify a first effective impedance of a load presented to the power amplifier via the output network.
