VT30-90~VT550-865 Electronically tunable filter
Frequency range: 30~1000MHz
1) This is the difference of %3dB bandwidth within the frequency band, see page 68-69 for typical curves.
2) Insertion loss at center frequency is typical value, the wider passband the lower IL. Following method is used to
calculate insertion loss: IL×BW3dB%=20~25, for example %BW is 5% then IL is 4~5dB.
3) See page 60-61 for typical curves.
