1) The insertion loss of DVT30-110-x to DVT550-865-x is related to 3dB fractional bandwidth, Center insertion loss×BW3dB%=20~25. For instance, 5% is 4-5dB;

2)The digitally controlled frequency hopping filter with internal D/A conversion realizes miniaturization and dense frequency hopping (251 points).
