CALIBRATION PROCEDURE
In order to calibrate PBN153/44, a double-track Network Analyser is needed, in order to visualize the
frequency response of the passing and reflected signals.
- Calibration procedure from 470MHz to 666MHz
1. Extract the coupling 5 (Fig. 1) until it stops.
2. Insert the couplings 3, letting about 5mm out.
3. Connect the filter to the Network Analyser marking the input. Select the frequency of the desired channel
centre and set a SPAN of 50MHz.
4. Act on the tuning rods 1 and 2 until the curve of the band-pass appears in the centre of the screeen, and
adjust it by means of the couplings 3 to obtain a width of about 10MHz (Fig. 2).
113
Fig. 2
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).
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).
114
Fig. 4
7. The adaptation has moved; it can be adjusted by acting on the filter as per point 6, correcting each time the
attenuation tuning by means of the coupling 5, until a frequency response like that in the example (Fig. 5) is
obtained.
Fig. 5
8. Once the calibration is complete, the machanical movement during the locking stage will have to be
compensator for, because a variation of the adaptation may occur. It only takes to extract slightly the tuning
which is being fastened.
115
- Calibration procedure from 66MHz to 860MHz
1. Extract the coupling 5 (Fig. 1) until it stops.
2. Extract the couplings 3 making sure not to short-circuit them.
3.Connect the filter to the Network Analyser, marking the input. Select the frequency of the desired centre
channel and set a SPAN of 50MHz.
4. Act on the tuning rods 1 and 2 until the curve of the band-pass appears in the centre of the screen and
adjust it by means of the coupling 3 to obtain a width of about 10MHz (Fig. 2). The tuning 2, due to the
elliptical system according to which the filter has been designed, will compose the attenuation of the notch as
well as the curve of the band-pass.
116
Fig. 2
5. Set a SPAN of 20MHz and act alternatively on:
- Interstage couplings 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).
Fig. 3
6. Use 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).
117
Fig. 4
7. It is possible to note that, by tuning the notch attenuation as described in point 6 above, the adaptation has
moved. It can be adjusted by acting on the filter as per point 6, correcting each time the tuning of the notch
attenuation by means of the coupling 5, until a frequency response like the one in the example (Fig. 5) is
obtained.
Fig. 5
8. Once the calibration is complete, the mechanical movement during the locking stage will have to be
compensated for, because a variation of the adaptation may occur. It only takes to extract slightly the tuning
which is being fastened.
