Note:

Insertion loss of VT30-110-x to VT550-865-x is related to 3dB fractional bandwidth. Center insertion loss×BW3dB%=20~25, for instance, 5% is 4-5dB;

The loss in the VT950-1450AE table is the actual loss value (including the built-in amplitude equalizer loss) in the full Frequency Range of the product.
