Cavity Filters High Frequency, Medium Bandwidth — FV Series

Attenuation:
The adjacent curve is used to determine the out-of-
band or stopband attenuation for K&L’s combline
filters. This curve shows the attenuation as multiples of
the 3 dB bandwidth for filters up to 13 sections. The
formula for approximate stopband attenuation:
3 dB BW from
f
0 =
Reject Frequency-Center Frequency
3 dB BW
Example:
Center Frequency = 6575 MHz
3 dB Bandwidth = 750 MHz
Number of Sections = 7
Find the attenuation at 5600 MHz and 7550 MHz by
substituting in the formula:
3 dB BW from
f
0
= 5600-6575 = -1.3 BW
750
3 dB BW from
f
0
= 7550-6575 = +1.3 BW
750
From the 7 section curves -1.3 BW and +1.3 BW yield
approximately 56 dB
