In order to have large coverage, the used radio communication requires high power output of radio frequency (RF) amplifier. This paper deals with the development of high power class-E amplifier implemented for radio communication of tsunami early warning systems (TEWS). The proposed amplifier is developed using a power laterally-diffused metal-oxide semiconductor (LDMOS) transistor of BLF188XR type from Am-pleon as the main component. The frequency range of developed amplifier is 90MHz to 110 MHz which is suited for proposed radio communication of TEWS. Some attempts to attain high power amplification are performed through a circuit EM simulator software. Based on the optimum performance, the proposed amplifier is then deployed on a printed circuit board (PCB) for experimental measurement. The result shows that the realized amplifier has the gain achievement more than 21 dB at the frequency of 100 MHz suitable for the desired application.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Class-E amplifier,High power amplification,High power output,Laterally diffused metal-oxide semiconductors,Optimum performance,Printed circuit boards (PCB),Simulator software,Tsunami early-warning systems[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research was partially supported by the Grant for Collaboration Research between Higher Education Institutions (Hibah PEKERTI) FY2018 Contract No. 020/SP2H/LT/DRPM/2018 from the Ministry of Research, Technology, and Higher Education, the Republic of Indonesia.
