DVT90-200-x 90-200
DVT200-400-x 200-400
DVT400-700-x 400-700
DVT550-865-x 550-865

DC parameters: Single Power supply Vcc: +3~3.6V/15mA.

Note:

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).
