5. Set a SPAN of 20MHz and act alternatively on:
- Interstage coupling 3 (rise and lower);
- IN/OUT couplings 4 (turn);
- Tuning 1 and 2 (rise and lower);
to obtain a bandwidth of 7-8MHz and an adaptation of about 25dB, composed by four peaks (Fig. 3).

6. Insert the coupling 5 (Fig. 1) to set the position of the notch attenuation on the desired frequencies (Fig. 4)
(5.5MHz and +11MHz or 4-5MHz and +9MHz).
