ACTIVE CROSS-BAND ISOLATION FOR A TRANSFORMER-BASED POWER AMPLIFIER

Embodiments of radio frequency (RF) systems include a plurality of power amplifiers having a primary winding and a secondary winding. Each of the power amplifiers may be configured to process signals of different frequency bands. The primary winding for one power amplifier can be detuned while anoth...

Zusammenfassung:	Embodiments of radio frequency (RF) systems include a plurality of power amplifiers having a primary winding and a secondary winding. Each of the power amplifiers may be configured to process signals of different frequency bands. The primary winding for one power amplifier can be detuned while another power amplifier is being used in a transmit mode. By detuning the power amplifier, power coupling from the transmitting power amplifier can be reduced or eliminated.
