Abstract
A series resonant circuit (17, 16, 22, 21, 19) is employed to minimize the area utilized to form an RF amplifier (10). The series resonant circuit (17, 16, 22, 21, 19) utilizes a capacitor (21) along with inductors (17, 19, 22) that are formed by bonding wires (17, 19, 22) which interconnect the components of the amplifier (10). The series resonant circuit is tuned to the second harmonic of the fundamental frequency applied to the RF amplifier (10). The area consumed by the series resonant circuit (17, 16, 22, 21, 19) is small thereby minimizing the amplifier's size.
