Abstract

Pada penyusunan sistem rangkaian transmitter radar,digunakan sistem rangkaian up-converter dua tahap yang terdiri dari, mixer 180 MHz, filter 200MHz, direct coupler, gain block amplifier, mixer 2.8 GHz, filter 3GHz, dan 2 power splitter sebagai input frekuensi osilator pada dua mixer yang digunakan. Up-converter berfungsi sebagai pengkonversi sinyal Intermediate Frequency (IF) atau sebuah sinyal yang memiliki frekuensi menengah menjadi sebuah sinyal Radio Frequency (RF). Untuk mixer sendiri bertujuan untuk mentranslasikan frekuensi IF menjadi frekuensi RF dimana mixer harus memiliki seleksivitas yang tinggi agar sinyal RF yang dihasilkan tetap.
Dalam perancangan rangkaian frequency up-converter menggunakan software Eagle untuk mendesain schematic dan layout PCB serta menggunakan software AWR Design Environment untuk simulasi dari rangkaian frequency up-converter.Tahapan yang dilakukan dalam perancangan frequency up-converter yaitu analisis datasheet komponen,lalu menentukan stack up layer PCB,lalu menentukan aturan RF pada desain PCB,lalu mendesain library komponen,lalu membuat layout pcb,lalu melakukan simulasi karakteristik parameter gain, noise, dan spektrum keluaran rangkaian dengan menggunakan sofware AWR Design Environment.
Hasil yang didapati berdasarkan tugas akhir ini yaitu dengan penerapan multilayer PCB, rangkaian frequency up-converter menghasilkan spektrum frekuensi ouput sebesar 3 GHz dengan karakteristik parameter RF berupa gain konversi sebesar 5.287 dB, dan noise figure 14.05 dB.

In the preparation of the radar transmitter circuit system, a two-stage up-converter circuit system consisting of a 180 MHz mixer, 200MHz filter, direct coupler, gain block amplifier, 2.8 GHz mixer, 3GHz filter, and 2 power splitters as oscillator frequency inputs to the two mixers used. The up-converter functions as a converter of Intermediate Frequency (IF) signals or a signal that has an intermediate frequency into a Radio Frequency (RF) signal. The mixer itself aims to translate the IF frequency into RF frequency where the mixer must have high selectivity so that the RF signal produced is fixed.
In designing the frequency up-converter circuit using Eagle software to design schematic and PCB layout and using AWR Design Environment software for simulation of the frequency up-converter circuit. The stages carried out in the design of the frequency up-converter are analyzing the component datasheet, then determining the PCB stack up layer, then determining the RF rules in the PCB design, then designing the component library, then making a PCB layout, then simulating the characteristics of the gain, noise, and output spectrum parameters of the circuit using AWR Design Environment software.
The results obtained based on this final project are that with the application of multilayer PCB, the frequency up-converter circuit produces an output frequency spectrum of 3 GHz with RF parameter characteristics in the form of a conversion gain of 5.287 dB, and a noise figure of 14.05 dB.
