"This book discusses the recent research developments of various passive microwave circuits on silicon substrate and demonstrated operations catering for multiple frequency bands. It covers the design, modelling, process fabrication and characterization aspects with practical examples. The book will be of use to researchers and engineers working in the field of RF or microwave engineering, who can use the techniques and approaches effectively without having to refer to multiple sources.

"[ABSTRAK
Telah dikembangkan hardware pada sistem RF Tomografi menggunakan VCO
(voltage controlled oscillator) MAX2750 sebagai komponen dasar transmitter dan
MAX2015 sebagai RPD (RF Power Detector). MAX2750 memiliki rangkaian
frekuensi tala (tuning frequency) pada internal VCO sehingga dapat
menghasilkan frekuensi yang dapat dikontrol oleh tegangan dari 2300 MHz
hingga 2500MHz. Pada penelitian ini analisa hasil pengukuran pada RPD saat
diberikan attenuator atau objek pengukuran yang berbeda diantara transmitter dan
receiver yang berbanding dengan pengukuran referensi atau hasil pengukuran
tanpa adanya objek. Rangkaian receiver terdiri atas MAX2015, ADC 16-Bit, dan
beberapa komponen pasif lainnya, dimana MAX2015 merupakan logaritmik RF
Detector yang dapat mendeteksi power pada frekuensi 0.1GHz hingga 3GHz.
Dalam penelitian ini frekuensi yang dipancarkan oleh RF Transmitter berada pada
frekuensi 2.3GHz hingga 2.5GHz, hal ini dilakukan berdasarkan referensi dari
beberapa jurnal dan penelitian yang dapat dipercaya. Dari hasil penelitian
didapatkan bahwa Antenna memiliki puncak respon maksimum pada frekuensi
2.4GHz, dimana objek yang digunakan adalah balok kayu, balok nilon, dan balok
alumunium dengan panjang 60mm, lebar 40mm, dan tinggi 80mm.

ABSTRACT
Has been developed a hardware in the system RF Tomography using a transmitter
VCO (voltage controlled oscillator) MAX2750as a basic component of transmitter
and MAX2015 as a RPD (RF Power Detector). The MAX2750 has an integrated
VCO with a fundamental output frequency ranging from 2300MHz to 2500MHz
that controlled by voltage. This research analyzed the measurement data for each
different attenuator or object interest whichamong of transmitter and receiver that
comparing with the reference data. Receiver circuit consists of MAX2015, ADC
16-Bit, and some pasif component, MAX2015 is a logarithmic RF Detector which
detect the power in frequency ranging 01.GHz to 3GHz. In this study the
transmission frequency ranging 2.3GHz to 2.5GHz, based on by using some
journals that have credibility as reference. Of the result showed that Antenna has a
maximum respons on frequency 2.4GHz, and the attenuator are a wood cube, a
nylon cube, and alumunium cube with length 60mm, width 40mm, and height
80mm, Has been developed a hardware in the system RF Tomography using a transmitter

"This book is intended as a report of my final project under the EEB889 subject. The objective of the project is to give an opportunity for student to gain experience in a situation similar to what would be encountered in the real workplace. The project involves investigation, planning, design, implementation, operation and testing over a time-frame of two semesters. This final project is about Radio frequency (RF) spread spectrum receiver using Phase Locked Loop (PLL). The progress of the project is monitored and assessed by Dr. John Edwards, Senior Lecturer in QUT faculty of Build Environment and Engineering (BEE). During the making of this project, I also had to study and do assignments from other subjects that I had taken for the last two semesters. I had done study and research through books, lecture notes, and internet regard to this project. I encountered many problems and difficulties to understand the whole pieces of the project and also to design and test the simulation and the circuit of the project. Thanks to my supervisor, Dr. John Edwards, who helped me to understand and solved the problems that I encountered."
