摘要： Integrated Doherty power amplifiers are provided herein. In certain implementations, a Doherty power amplifier includes a carrier amplification stage that generates a carrier signal, a peaking amplification stage that generates a peaking signal, and an antenna structure that combines the carrier signal and the peaking signal. The antenna structure radiates a transmit wave in which the carrier signal and the peaking signal are combined with a phase shift.

摘要： Aspects and examples described herein provide a variable gain amplifier circuit and assembly. In one example, a variable gain amplifier circuit includes a signal input, a signal output, and a variable gain amplifier including a plurality of unit cell groups coupled between the signal input and the signal output, the variable gain amplifier configured to provide an adjustable gain to a signal received at the signal input during each of a plurality of amplify modes of the variable gain amplifier, each of the plurality of amplify modes corresponding to at least one unit cell group of the plurality of unit cell groups. A bypass path including a fixed attenuator is coupled in parallel with the variable gain amplifier between the signal input and the signal output to selectively couple the signal input to the signal output through the fixed attenuator during a bypass mode.

摘要： Systems and methods for differential antenna driving are provided. In one aspect, a front end system includes at least one power amplifier configured to receive a first transmit radio frequency signal from a baseband processor, amplify the first transmit radio frequency signal, and output the amplified first transmit radio frequency signal. The front end system further includes at least one balun configured to receive the amplified first transmit radio frequency signal. The at least one balun includes a positive output coupled to a first monopole of at least one antenna and a negative output coupled to a second monopole of the at least one antenna.

摘要： A differential circulator comprises first and second magnets, a ground plane, a first three-port junction conductor disposed between the first magnet and the ground plane, and a second three-port junction conductor disposed between the second magnet and the ground plane. The first three-port junction conductor and the second three-port junction conductor are in the same magnetic circuit including the first and second magnets to provide substantially same pass characteristics to radio frequency signals passing through the first three-port junction conductor and the second three-port junction conductor.
