Multiple Realizations of Cascaded Filters

This model shows three different ways to use RF Blockset™ Equivalent Baseband library blocks and RF Toolbox™ objects to implement filters.

Example Model

Example model of multiple realizations of cascaded filters:

The first method creates a filter using transmission line blocks from the Transmission Lines sublibrary and a LC Bandpass Filter block from the Ladder Filters sublibrary.

The second method creates a filter using three General Circuit Element blocks and three RF circuit objects.

The third method creates a filter using a General Circuit Element block and an RF circuit object, which represents a cascade of three RF circuit objects.

Simulation Results

The spectrum scope shows the frequency responses for the three filter implementations from 70 MHz (-5.0 MHz) to 80 MHz (5.0 MHz).
