ABSTRACT:
Linearity and efficiency of a radio frequency multi-stage power amplification device 10 are increased by employing two tuned circuits 16 and 18 in the driver stage 12 and two tuned circuits 22 and 24 in the high power stage 14. After selecting elements of tuned circuits 22 and 24 in order to optimize the high power stage 14 for efficiency, linearity, and power output, elements are selected for tuned circuits 16 and 18 in order to cause the intermodulation output components associated with the driver state 12 to have a 180.degree. phase angle relative to the intermodulation output components associated with the high power stage 14. This phase angle relationship will cause the intermodulation output component products from the driver 12 and high power stages 14 to cancel.
