Amplifier with Variable Feedback Impedance |
摘要 |
A variable feedback impedance is presented capable of providing high linearity (e.g. as represented by 1P2 and 1P3) and high linear range (e.g. as represented by P1dB) when used in a feedback path of an RF amplifier in the presence of high voltage amplitudes. |

1. A radio frequency (RF) amplifier arrangement comprising:
an RF amplifier; one or more resistive and/or reactive components within a feedback path between an output terminal and an input terminal of the amplifier; and one or more stacked transistor switches within the feedback path configured to select an impedance value of the feedback path from a plurality of selectable impedance values. |
