A radio frequency (RF) power amplifier includes a low impedance pre- driver (513) driving the input of a common- source output amplifier stage (514). The preamplifier (513) includes a first transistor (502) that has a first terminal coupled to a preamplifier RF input node (501), a second terminal coupled to a preamplifier RF output node (503), and a third terminal coupled to a supply voltage node (515). A first inductor (504) is coupled between the RF output node (503) and a bias voltage node (505). A voltage difference between respective first and second voltages on the RF input node (501) and the RF output node (503) that are substantially in phase, determines current through the first transistor (502). |

A circuit, a method and an apparatus, are described. A radio frequency (RF) signal received from a transmission line is provided to the source of a transistor in a common-gate amplification circuit. A series resonance connected to the source provides a low impedance path to ground for interfering RF components in the RF signal. The series resonance is tuned to provide a high impedance to a band of frequencies centered on a frequency of interest and to shunt interfering RF components outside the band of frequencies centered on the frequency of interest. The interfering RF components may include a harmonic of the frequency of interest. |
