INTISARI

Pada sistem komunikasi nirkabel, pemancar dan penerima merupakan komponen

mendasar yang berperan dalam telekomunikasi. Sistem penerima berfungsi untuk

menerima suatu sinyal informasi. Struktur dasar sistem penerima yaitu : Antena – Low

Pass Filter – Low Noise Ampifier (LNA) – Mixer – Phase Lock Loop (PLL) –

Demodulator – Audio Output.

Dalam skripsi ini menjelaskan tentang Receiver RF Circuit Training System GRF-

3300 dengan bahasa yang mudah dimengerti yang meliputi cara kerja dan fungsi pada

alat peraga sistem penerima serta modul-modul struktur dasar yang digunakan dalam

sistem penerima, sehingga dapat membantu mahasiwa teknik elektro khususnya teknik

telekomunikasi dalam memahami sistem penerima.

Receiver RF Circuit Training System GRF-3300 akan menghasilkan nilai Total

Harmonic Distortion sekitar 5% jika dengan masukan sebesar 1Vrms.

Kata Kunci : penerima, total harmonic distortion

ABSTRACT

In wireless communication systems, transmitters and receivers are fundamental

components that play a role in telecommunications. The function of receiver system is to

receive an information signal. The basic structure of the receiving system are : Antenna

– Low Pass Filter – Low Noise Ampifier (LNA) – Mixer – Phase Lock Loop (PLL) –

Demodulator – Audio Output.

This study describes RF Circuit Training System receiver GRF-3300 through

easy-to-understand language that includes the workings and functions of the receiver

system props as well as the basic structure modules used in the receiver system, so as to

assist students of electrical engineering especially telecommunication engineering in

understanding the receiver system.

RF Circuit Training System receiver GRF-3300 will produce Total Harmonic

Distortion value about 5% if input about 1Vrms.

Keywords : receiver, total harmonic distortion
