ECE U574 - Wireless Communication Circuits

Institution:

Northeastern University

Subject:

Description:

Explores analog radio electronics through the design and construction of a 7 MHz radio transceiver (the NorCal 40A). Offers an overview of radio designs and components. Describes the phasor analysis of series and parallel resonant circuits. Presents transmission line concepts including phasor analysis for waves, the telegraphist's equations, dispersion, resonance, quality factor, and lines with loads. Introduces radio filter designs including ladder filters, band-pass filters, as well as filters using crystals and impedance inverters. Introduces working concepts of transformers and speakers. Describes transistor switches and Class B, C, D, E, and F amplifiers. Presents the fundamentals of oscillators and mixers. Also discusses antennas and propagation fundamentals including impedance, Friis's formula, and reciprocity. Dipole and whip antennae are used as practical examples.
