Like all of our products we use high tolerance, high quality components and the latest manufacturing methods to produce quality, consistent filter modules.
Frequency - A range of modules covering the range DC - 1 MHz
Matching between filter modules depends on frequency, filter response and other factors, but typical figures of +/- 0.1 dB , and +/- 1 degree of phase, in the passband are usual. In some cases we are measuring differences between filter modules of milli dB!
Kemo filter modules are continuous time filters, we DO NOT use switched capacitor techniques, and our filter modules do not use any clock signals.
Technical details, including pin outs, layouts and typical application circuits are available at the Filter Modules Connection Details section.
We try to keep a range of Standard Filter Responses in stock.
