◆ Insertion Loss:The insertion loss at the center frequency of the filter isdetermined by the equation:
Loss = (Loss Constant) (No. of Sections + 0.5) +.3% 3 dB BW
Where the loss constant is frequency dependent and maybe found from the table to the side.
Example:
At 500 MHz, 5 sections, 60 MHz BW
Loss = (4.4)x(5.5) +0.3 = 2.3 dB12

Lumped Components, Microminiature Bandpass — IB Series
◆ Attenuation:
These curves show the attenuationnormalized to the 3 dB bandwidth for filterswith 2-8 sections. The following formula isused: 3 dB bandwidths from centerfrequency =
Reject Frequency - Center Frequency3 dB BW
Example:
Center Frequency = 500 MHz3 dB Bandwidth = 60 MHzNumber of Sections = 5Find the attenuation at 400 and 600 MHz bysubstituting in the formula 3 dB bandwidthsfrom center frequency = 400-500 = -1.67 BW’s
60and 3 dB bandwidths from centerfrequency = 600-500 = +1.67 BW’s
60
From the 7 to 15 % curve we find theattenuation in dB for a 5-section response -1.67 BW’s from center frequency yields60 dB, and +1.67 BW’s from centerfrequency yields 34 dB.
