Description including Unit Aims
The aim is to provide an introduction to the theoretical and practical aspects of RF and microwave circuit design. This includes a detailed study of RF transistor amplifier design, covering RF transistor behaviour and selection; Smith Chart design of small-signal amplifiers using lumped-element and stub matching techniques; and RF power amplification and linearity considerations in RF systems.
- Components at RF, resonant circuits; Q factor, Fixed Q, High Q and low Q impedance matching; Semiconductors at RF and BJT models at RF; s-parameters.
- Small-signal RF amplifier design: bias networks, stability and matching.
- Smith chart matching network design.
- Amplifier design using Smith charts: stability, gain control and matching network design.
- Low-noise design: choice of bias point and noise figure.
- Principles of microwave systems; microwave amplifier design; Transmitter architectures; Amplifier distortion: modelling, intercept point, harmonic and inter-modulation distortion.
- Large-signal RF amplifier types and classes.
