+5V/90mA

V_bb:+15~100V/1.5mA

Note: 1) This is the difference of % 3dB bandwidth within the frequency band, see Page 56 for typical curves

2) Insertion loss at center frequency is typical one, the wider passband the lower IL. Following method is used to

calculate insertion loss：IL ×BW_3dB%=20~25, For example % BW is 5% then IL is 4~5dB

3) See typical curves on page 56

4) Decided by the bias voltage, refer to the “Input P_-1--- Bias voltage”typical curve on page 55
