Bandpass Specification

As an example, we assume that we have the following design specification.
Specification
Passband 1710 MHz - 1785 MHz
Return loss > 16 dB
Through loss < 0.9 dB
Stopband 1805 MHz - 1880 MHz
Stopband attenuation > 70 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 the "Return Loss" we enter 20 dB so that we have some spare for later design steps (EM simulation).
- The stopband specification can be entered in the "Approximation" window.
