Programmable radio frequency predistortion linearizer and method thereof |
摘要 |
A radio frequency (RF) predistortion linearizer with a transistor and a control circuit, an input matching circuit and an output matching circuit. The control circuit is electrically coupled to a control voltage source that supplies control voltages via a control node. A resistor and a coupling inductor electrically couples the control circuit to the control node to receive the control voltages. These control voltages set two varactors of the control circuit to provide a capacitance. The capacitance and an inductance provided by an inductive block of the control circuit can thus provide a resonant frequency. This resonant frequency is thus controllable and is based on a centre frequency of an RF input signal provided to an input node of the RF predistortion linearizer. |
