MODUL PENGUAT DAYA RF 15 WATT (RANGKAIAN BUFFER)

RF power amplifier is a device which have function to amplify the signal frequency. The example of application RF power amplifier is transmitter. The tool design for module have purpose to support practical activity in telecommunication laboratory. To create this module, then designed driver circuit which has function as first level of amplifier in circuit module that designed. This circuit is using A class amplifier with 2SC121 transistor as the main component, this component has output power maximum 400 mW. The result which obtained from the experiment state that the driver is working optimally in the range frequency 1 MHz to 3 MHz with the gain power occured at a frequency of 2 MHz with a power input in -10 dbm is 30,1 dB and the biggest voltage gain is at 1 MHz with the power input -10 dbm is 34,8 dB.
