A low Vbb can cause errors of tune words so that you must declare to the factory of the exact Vbb used to adjust the errors before delivery. 1) The Input P-1 decided by the bias voltage, refer to the “Input P-1-Bias voltage”typical curve on this page 2) Replacement alternative for MICRO-POLE series of POLE/ZERO 3) Zero DC resistance at both I/O port, additional DC blocking capacitance needed if necessary T ypical Curves Input power (P-1) via Vbb LBM017A -85(40-110MHz) f=1 10 MH z 20 15 10 15 30 25 35 30 45 60 100 85 f=4 0M Hz f=6 0M Hz Bias Voltage (V) LBM037A-85 (30-90MHz) 15 10 20 15 30 25 35 85 45 f=6 0M Hz f=3 0M Hz f=9 0M Hz 30 60 100 Bias Voltage (V) LBM039A -85(90-200MHz) f=20 0MH z 25 20 15 10 15 30 f=90 MH z 35 30 f=1 50M Hz 45 60 100 85 Bias Voltage (V) LBM040A-85 (200-400MHz) 15 10 15 25 20 35 30 45 30 f=2 00 MH z f=3 00 MH z f=4 00 MH z 60 85 100 Bias Voltage (V) |
