+3.3V/15mA
Note: 1) difference of % 3dB bandwidth within the frequency band, see Page60-61 for typical curves
2) Insertion loss at center frequency is typical one, the wider passband the lower IL. Following method used to calculate
insertion loss：IL ×BW_3dB%=20~25, For example % BW is 5% then IL is 4~5dB
