Abstract

Power amplifier (PA) is the final component in the DITTEL Portable VHF transmitter with fucuntion to amplify the signal that is sent from the source. In this paper, the power amplifier is made to work at a frequency of 135 Mhz. PA proposed using Type Mosfet transistors MRF 136 with power supply V = 30 V, VDD = 28 V and ID = 1.2 A in order to obtain the gain and output power are great. To boost the coverage area of communication at the time of check calibration flight. Design PA using L-Network and phi- Matching is used as an input matching circuit and output matching. Type bias transistor used is a power-divider because it has the sensitivity of the lowest changes to temperature changes. The results of the simulations and calculations have been carried out, the result obtained from the specification of power amplifier : stability values> 1, the gain (S21) = 20 dB, output return loss (S11) = -33.89 dB. With a power output as expected at 10 watts or 40 dBm at frequency 135 MHz.

Abstract

“Design of Remote-Control Monitoring System (RCMS) on NDB Air Navigation equipment in Makassar Branch Cluster (MATSC) based on Internet of Thing (IoT)”. The benefits of RCMS include; Can assist maintenance technicians in carrying out maintenance tasks at a certain level, as a form of synergy and collaboration between the aviation industry and vocational education, with this RCMS, better data will be obtained for further research. The objectives of this design are; Designing a Remote Control and Monitoring System (RCMS) for NDB Hanjin KMW 250 RB, implementing science and technology as a form of collaboration between the education world and the aviation industry, Providing equipment maintenance data for maintenance management purposes. And in control directly in the technician's room to make it easier to monitor NDB Navigation Equipment. This design method is based on the Internet of Thing (IoT) The results of this design are able to provide a display of the parameters of the Air Navigation Equipment (NDB) in the Makassar Branch (MATSC),
