Abstract

The RF power amplifier has been designed and realized to operate at the frequency of 100 MHz with 1000 mW of power output at 12 V supply voltage in this research. Based on this design, it will be used to design of the RF power amplifier with large output power at desired frequency operation. The RF power amplifier consist of three stages amplification, with first amplifier is operated in class A, second and third amplifier are operated in fixture mode class C. Class A amplifier is designed with using the procedure that presented by Purdie, while fixture mode class C amplifier is designed by using of large signal transistor impedance. Realizing of the RF power amplifier can be able to used for amplifying signal of 100 MHz. The measurement of the RF power amplifier at 12 V supply voltage; maximal output power of 1148,15 mW; second harmonic distortion of 0,07 %; bandwidth 8 MHz and signal power are larger then noise that generated by the amplifier.
