RF Circuit Design

Unit 1

INTRODUCTION:

Reasons for using RF, Applications, RF Spectrum, Microwave bands-RF behavior of Passive components: Tuned resonant circuits, Vectors, Inductors and Capacitors-Voltage and Current in capacitor circuits-Tuned RF / IF Transformers. Micro Strip Transmission Lines-Special Termination Conditions-sourced and Loaded Transmission Lines.

UNIT-IIRF/MICROWAVE AMPLIFIERS:

Types of amplifiers-small signal amplifier design-design of different types of amplifiers - narrow band, high gain, maximum gain, low noise broad band amplifier design - Multistage small signal amplifier design, Minimum Noise Multi stage amplifier design, Large signal design, High power amplifiers, Microwave power combining/dividing techniques, signal distortion due to intermodulation products, Multistage amplifiers large signal amplifiers design

UNIT-IIIRF OSCILLATORS:

RF/Microwave oscillator design-Oscillator versus amplifier design-oscillations conditions, design of transistor oscillators, fixed frequency, Frequency tunable oscillators.

UNIT-IVRF CONVERTERS AND MIXERS:

Rectifier design-detector design Formulation, Properties of S Parameters, Smith charts, applications on distributed circuit applications, lumped element circuit applications. Mixer design-UP conversion, down conversion, Conversion loss for SSB Mixers, SSB verses DSB Mixers conversion loss, one diode mixers, two diode mixer

UNIT-VRF MATCHING NETWORKS:

Design of matching networks using lumped elements, design rules for matching networks, Using distributed elements -using single stub matching Short or Open circuited stubs.
