    摘要: In a CO2 gas discharge laser energized by a radio frequency (RF) power source a transformer having selectively variable output impedance is used to match output impedance of the power source to the impedance of discharge electrodes of the laser. A similar transformer can be used to impose a selective variable phase-shift on the RF power from the source. The variable impedance transformer can also be used for impedance matching between amplifier stages in the power source.

    摘要: An RF amplifier circuit includes a MOSFET connected to an RF output of the circuit via an impedance matching network including an inductor and a tuning capacitor connected in parallel with the inductor and the MOSFET. DC voltage is applied to the MOSFET via a series path through a radio frequency choke and the inductor of the impedance matching network.
