An RF power amplifier includes a first amplifier module comprising a first push-pull amplifier including a first plurality of field effect transistors and a first output transformer. An output impedance of the first amplifier module is 25 ohms. A second amplifier module includes a second push-pull amplifier including a second plurality of field effect transistors and a second output transformer. An output impedance of the second amplifier module is 25 ohms. A combiner is connected to the first amplifier module and the second amplifier module. The combiner combines an output from the first amplifier module and an output from the second amplifier module into a combined signal. An output impedance of the combiner is 50 ohms.       Recently Added Patents Link analysis compliance and calibration verification for automated printed wiring board test systems Dual flow pressure washer Photonic interconnect method Shift frequency demultiplier with automatic reset function Universal junction box Derivative products Power bank apparatus with speaker   Randomly Featured Patents Nonlinear optical element Immunologically active polypeptides with altered toxicity useful for the preparation of an antipertussis vaccine Kentucky bluegrass Liquid sampling pipette with adjustable ejector Apparatus for dressing and slaughtered bird Method and system of testing electronic device Diagnostics for resistance based transmitter Device for interconnecting vessels in a patient Bridge plug Electrode-less discharge lamp © 2006-2008 PatentGenius.
