Dual Bandpass Specification

As an example, we assume that we have the following design specification.
Specification
Passband I 1650 MHz - 1700 MHz
Passband II 1800 MHz - 1850 MHz
Return loss > 16 dB
Through loss < 1.5 dB
Stopband I 1550 MHz - 1630 MHz
Stopband II 1720 MHz - 1780 MHz
Stopband III 1870 MHz - 1950 MHz
Stopband attenuation > 50 dB
- The specification is in the "Original Frequency" therefore we select this option.
- The passband information can be entered at "Start" and "Stop" frequencies
- For a dual bandpass the tab "Zero" has to be selected.
