Tune words from 00000000 to 11111010 results in the tuned frequency from lowest to highest Tuneword = ⎟ low high low desired f f f f ×250 (Note: It will be 200 fo r LBM039A-85~LBM700A-85) Example：The tuneword of LBM037A-85 at fc=50MHz is： Tuneword = ⎟ 30 90 30 50 ×250=83D=53H Notes The accuracy of tune words is assured only with V bb=85V which is the case of manufacture. A low V bb 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 Typical Curves Input power (P-1) via Vbb LBM017A -85(40-110MHz) f=110MHz20
