Miniature Lumped Component Bandpass Filter
5~9% 3dB Bandwidth
Calculating Degression
Using the right graph to calculate the degression.
These curves show the relation between degression
and 3dB bandwidth.The following formula is used
to calculate the degression:
Number of 3dB BW =
fs - fc
3dB BW
Example:
Center Frequency(Fc):500MHz
3dB BW:60MHz(Fc±30MHz, 12% Fc )
Number of Section: 5
Calculating degression at Fs of 400MHz and
600MHz
Number of 3dB BW at 400MHz =
NUMBER OF 3dB BANDWIDTH
9~20% 3dB bandwidth
400 - 500
= - 167
.
60
Number of 3dB BW at 600MHz = 600 - 500 = +167
.
60
Using the 3dB bandwidth 9~20% to find the regression
at -1.67BW 's is 47dB and 34dB at +1.67BW 's.
Note: 1.The right two cluster of curves are for standard
response.
2.Contact the factory for the degression of the
filter with a 3dB bandwidth wider than 20% Fc.
NUMBER OF 3dB BANDWIDTH
Case Styles
70 Case styles available in stock, which include drop-in, SMT, SMA connectors(see more detail on page2-8).
Multi-section construct depends on the dimension in some degree. Following table shows the number of

Application Notes
1. Interchangeable RF I/O ports
2. Exceeding the absolute maximum ratings of 230 ℃ when mounting may casue damage of the filter.
3. Tested results of stop band rejection can only be displayed as 40dBc, which will be better to meet the
specs after soldering.
4. The stopband rejection can only be guaranteed as 50dBc for this two type of packages.

Number of 3dB BW = 1024-1000 = +2

The curve indicates that the degression is
31.6dBc for 3 sections filter at -2 BW and
30.7dBc for 3 sections filter at +2BW 's
Note:
1) The curves are for standard response with 1% 3dB
bandwidth.
2) Contact the factory for a wider span degression of
the filter.
3) A maximum stopband degression -60dBc guaranteed
4) Typical parasitic passband is 2.1~2.9Fc. The higher
frequency and wider pass band the nearer parasitic
passband.
Typical 50dB attenuation
2.7Fc (Fc<500MHz), 2.5Fc(Fc<1GHz), 2Fc(Fc<2GHz),
1.5Fc(Fc<3GHz), 1.3~1.5Fc (Fc =3~5GHz)。
Note
1. Interchangable input and output connectors.
2. Overheated will damage the component.
3. Low pass filter can be cascaded to eliminate the parasitic passband. The filters with extra internal
lowpass filter named as "-NLP", "-KLP", "KHLP".
4. Special requirement on dimension available.

Note:
1) The dimension listed in the tables is for
the filter with Fc<2500MHz. The center
freq. higher than 2500MHz will result
2N(mm) shorter in L(D).
2) If release the requirement on IL and
stopband degression for the filter with
Fc<2500MHz, a smalla L(D) can be
achieved by selecting the type of
dielectric resonators.
3) L will be 12mm longer than the standard
one for an extra external lowpass design.

Note:
1) Without special desire of W=23 from the customer,the W
will always have the corresponding default value of 29 and

2) The additional SMA connector will be impossible for the
package with W=23.
3) Two additional fixing holes are placed as the following rule:
if W=23, then two holes are placed at A=20.6. For a 5-7
section, Fc<2500MHz filter,two holes are placed at A=4.85.

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.

Notes:
A0~A7 are 8 control bit lines. Tune words from 00000000 to 11111010 results in the tuned frequency from
lowest to highest. The binary tuning word is determined by the following relationship:
Tuneword =
f desired f low
×250
f high f low
Example：If you wish to tune to 50MHz using a 30 to 90MHz filter, the tune word is：
50 - 30
×250=83D=53H
90 - 30
Application Notes
1) The relationship between tuneword and frequency is only an approximate one.
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.

Note:
1) This is the difference of % 3dB bandwidth within the frequency band, see Page 44 for typical curves.
2) Insertion loss at center frequency is typical one, the wider passband the lower IL. Following method.
used to calculate insertion loss not including the switching loss: IL×BW3dB%=20~25. For example
% BW is 5% then IL is 4~5dB , Loss of switch is about 3dB.
3) Decided by the bias voltage, refer to the ″Input P-1―Bias voltage″typical curve on page 46.
4) Current saving mode available, which can low the current down to 90mA.

Note:
1) A8~A9 are sub-band selection control bit lines. The words of Sub1, Sub2, Sub3 are 00B, 01B, 10B
respectively. The word 11B is for blocking.
2) A0~A7 are 8 inband control bit lines. 0000000 control the lowest frequency FAH(<90MHz) or C8H
(>90MHz) control the highest frequency.
3) The binary tuning word is determined by both inband tuneword and frequency band slection word
Tuning word in sub-band=
f desired f low
f high f low
×(hopping step of subband)
For example：The sub frequency band of LBM043A-512US is：30-90MHz, 90-200MHz, 200-512MHz,
the tuning word of fc=100MHz is calculated as following:
Tuning word in sub-band=
100 - 90
×250=23D=17H ，
200 - 90
Band selection word is 01B.
Then the full tuneword of A0~A9 at center frequency 100MHz is 117H.
Application Note
Please refer to the application notes of LBM017A-85~LBM700A-85 series (Page 62).
