Abstract
Switchable feedback circuit for radio-frequency (RF) power amplifiers. In some embodiments, an RF power amplifier (PA) circuit can include a transistor having a base, a collector, and an emitter. The transistor can be configured to amplify an RF signal. The RF PA circuit can further include a switchable feedback circuit implemented between the collector and the base. The switchable feedback circuit can be configured to provide a plurality of resistance values between the collector and the base. Such a PA circuit can be implemented in products such as a die, a module, and a wireless device.
