Designing Cascades

You can build a receiver or transmitter cascade from blocks specified by physical properties, mathematical behavior, or a mixture of both. Matching between blocks from the Mathematical library is assumed to be perfect, and so no reflections occur. In contrast, any imperfect matching and reflections between Physical library blocks are taken into account. The Input Port and Output Port blocks act as gateways to and from the physical parts of the model.

Mathematical and Physical libraries in RF Blockset. You can use mathematical equations and physical properties to represent the RF component. Click on image to see larger view.

If your network of components cannot be described as a simple cascade, you can configure RF Toolbox components as series, parallel, cascade, hybrid, or inverse hybrid subnetworks, using nesting if necessary, and then use the resulting subnetworks as part of an RF Blockset cascade.

The blockset also calculates noise figures and third-order intercept points (IP3s) for cascaded components. The link budget plot enables you to visualize the effect of individual components on the cascade, to assist optimum gain and filter distribution.
