LOW OUTPUT IMPEDANCE RF AMPLIFIER |
摘要 |
A radio frequency (RF) power amplifier includes a low impedance pre-driver driving the input of a common-source output amplifier stage. The preamplifier includes a first transistor that has a first terminal coupled to a preamplifier RF input node, a second terminal coupled to a preamplifier RF output node, and a third terminal coupled to a supply voltage node. A first inductor is coupled between the RF output node and a bias voltage node. A voltage difference between respective first and second voltages on the RF input node and the RF output node that are substantially in phase, determines current through the first transistor. |
