This thesis includes the study of hybrid microwave integrated circuits (HMIC), miniaturization techniques applied on HMICs and its application on a frequency modulated continuous wave (FMCW) range sensor transceiver. In the scope of
study, hybrid and monolithic microwave integrated circuits (HMIC and MMIC) are introduced, advantages and disadvantages of these two types are discussed. Large
size of HMICs is the main disadvantage especially for military and civil applications requiring miniature volumes. This thesis is mainly devoted on miniaturization work of HMICs in order to cope with this problem. In this scope, miniaturization
techniques of some HMICs such as 3 dB hybrid couplers and stubs are examined and analyzed. Their simulation and measurement results cohere with original circuit
results. Nevertheless, considerable size reduction up to 80% is achieved. Moreover, planar interdigital capacitors (IDC), spiral inductors (SI) and their equivalent circuit
models are introduced. Design technique is discussed with illustrative electromagnetic (EM) simulations. Furthermore, FMCW radar is introduced with its
basic operation principles, brief history and usage areas. In addition, FMCW range sensor transceiver is designed with its sub& / #8208 / parts / power amplifier, low noise amplifier (LNA), coupler and front end. Multi technology based on chip transistors,
interdigital capacitors, spiral inductors and hybrid couplers with wire& / #8208 / bond connections is used in the design. As the result of using hybrid miniaturized components small layout size is achieved for the transceiver system with its all
components.
