Description Design of a radio system for transmission of information; types of receivers, matching techniques, oscillators, design using 2-port network parameters, receiver and antenna noise, nonlinear effects, frequency synthesis.
Credit 4 hours
Goals The purpose of this course is to teach senior students in electrical engineering the basic principles of radio-frequency circuit design and to illustrate how such circuits are used in communication systems.
Topics
  • Receiver systems: modulation schemes; receiver fundamentals; superheterodyne receiver
  • Resonant circuits and impedance transformations
  • Oscillators: hybrid Pi model for BJT and FET; loop gain analysis; negative resistance analysis
  • Impedance matching: L networks, PI and T networks (lossless and attenuating); Smith chart
  • High frequency amplifier design: 2 port models - Y, Z, H, S parameters; stability, power gains, simultaneous conjugate matching
  • Noise characterization of systems: introduction to thermal noise characteristics; noise characterization of linear 2 ports; sensitivity of receiving system; measurement techniques
  • Nonlinear effects: 1 dB compression; two-tone response of nonlinear system, third-order intercepts; dynamic range of receiving system
  • Mixers: active mixers; switching type mixers; 4-diode double balanced mixer; conversion loss, nonlinear effects
  • Phase-locked loops and applications: FM detection; frequency synthesis
Computer Usage CAD Software (HP Microwave and RF design systems) is used in the laboratory.
Lab Projects Design, construct, match, and test a crystal oscillator and a radio-frequency amplifier operating at approximately 50 MHz; noise measurements; laboratory notebook required; instrumentation: vector impedance meter, spectrum analyzer, network analyzer, synthesizers.
Lab Equipment vector impedance meter, spectrum analyzer, network analyzer, frequency synthesizers.
