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 lossIL xBW3dB%=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

Dimension and Pinout
LBM017A-85~LBM700A-85 have a same outline and pinout as LBM034A~LBM700A LBM017A-85~LBM700A-85 Vbb=15~100V Note: A0~A7 are 8 control bit lines. Tune words from 00000000 to 11111010 results in the tuned frequency from lowest to highest Tuneword =
f desired - f low f -f low high
x250 (Note: It will be 200 for LBM039A-85~LBM700A-85)
ExampleThe tuneword of LBM037A-85 at fc=50MHz is Tuneword =
50 - 30 x250=83D=53H 90 - 30
Notes
The accuracy of tune words is assured only with Vbb=85V which is the case of manufacture. 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-1Bias 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
