Abstract: A radio frequency (RF) system includes an RF power amplifier (PA), which uses an envelope tracking power supply voltage to provide an RF transmit signal, which has an RF envelope; and further includes an envelope tracking power supply, which provides the envelope tracking power supply voltage based on a setpoint. RF transceiver circuitry, which includes envelope control circuitry and an RF modulator is disclosed. The envelope control circuitry provides the setpoint, such that the envelope tracking power supply voltage is clipped to form clipped regions and substantially tracks the RF envelope between the clipped regions, wherein a dynamic range of the envelope tracking power supply voltage is limited. The RF modulator provides an RF input signal to the RF PA, which receives and amplifies the RF input signal to provide the RF transmit signal.

Abstract: RF circuitry, which includes a first acoustic RF resonator (ARFR), a first compensating ARFR, and a second compensating ARFR, is disclosed. The first compensating ARFR is coupled between a first inductive element and a first end of the first ARFR. The second compensating ARFR is coupled between a second inductive element and a second end of the first ARFR. The first inductive element and the second inductive element are negatively coupled to one another. The first compensating ARFR, the second compensating ARFR, the first inductive element, and the second inductive element at least partially compensate for a parallel capacitance of the first ARFR.

Abstract: A radio frequency (RF) power amplifier (PA) and an envelope tracking power supply are disclosed. The RF PA receives and amplifies an RF input signal to provide an RF transmit signal using an envelope power supply voltage. The envelope tracking power supply provides the envelope power supply voltage based on a setpoint, which has been constrained so as to limit a noise conversion gain (NCG) of the RF PA to not exceed a target NCG.
