DC power:
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 ×BW3dB%=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

Example:The tuneword of LBM037A-85 at fc=50MHz is:

⎝ 90 − 30 ⎠
Tuneword = ⎛⎜
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-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
