Single-Course English 10 ECTS

RF communication circuits

Overall Course Objectives

To introduce RF communication circuits, their design concepts in discrete or integrated realizations, and the trade-off between circuit technology and communication systems requirements. The student will be able to design RF communication circuits or subsystems based on component, circuit, and system data and specifications.

Learning Objectives

  • explain principles of the most common radio transmitter and receiver systems
  • design frequency selective networks using narrow band approximations and series-to-parallel conversions
  • construct RF impedance matching and transformation circuits using discrete components
  • design stable small-signal RF amplifiers
  • calculate noise-figure and dynamic ranges of amplifiers from component data
  • explain basic RF power amplifier principles and conduct simple design calculations
  • design simple RF-oscillators using LC and crystal resonators
  • explain mixer principles and conduct basic design calculations.

Course Content

RF signals and circuits, including linear amplifiers, mixers, oscillators, detectors, limiters, and power amplifiers. Transmitter and receiver structures. Design of RF integrated circuits. Circuit concepts like stability, noise, distortion, intermodulation, and dynamic range. System concepts including signal to noise ratio, thresholds, and bit error rates. Circuits, which are used in Bluetooth, WiFi, Internet of Things (IoT), 5G communications, Connected Cars, radars, medical and biomedical instruments and many others.
