Sub-Miniature Bandpass

All of the filters tabulated on this page are specified as having a minimum band width at the - 3 dB points and a maximum band width at the -20 dB and -40 dB points. Most of the Bandpass Filters on this page do not exhibit arithmetic or geometric symmetry. However, to insure our customers of a simple method of determining their requirements, we are specifying the -3 dB, -20 dB and -40 dB bandwidths as if all had arithmetic symmetry. This will guarantee at least 1/2 of the 3 dB passband will exist on each side of the center frequency. The -20 dB and -40 dB points will be no greater ±1/2 of their respective bandwidth away from their center frequency.

Filter Center Frequency (F₀)

Can be any 3 digit number from 10 MHz to 500 MHz. "P" represents the decimal point and must be used in the second, third or fourth location.

3 dB Bandwidth (F_c)=F₀/Q

Can be any 3 digit number up to 125 MHz (a center frequency of 500 MHz with a Q of 4.) "P" represent the decimal point and must be used in one of the four locations. The specified bandwidth must be within the limits of the tabulated Q. (See examples below)

4P50

Example: MB-99P5-4P50-A-SThis part number describes a Bandpass Filter having its center frequency at 99.5 MHz and having a 3 dB bandwidth of 4.50 MHz with a "A" shape factor and SMA Connectors. Note in tabulation below that for a center frequency of 100 MHz, and a shape factor of "A", a Q of up to 30 is realizable.
