Switched Filter Bank RF Pre-selector (20 - 1200 MHz) Features • • • • • Description Excellent IMD Suppression Low Insertion Loss: 4.5 dB Ripple: 0.8 dB Fast Switching: 1 µSec 60 dB Isolation Bit Signal & to RF Signal Typical Specifications Spectrum Microwave’s 310-020008-001 Switch Filter-bank provides two separate signal paths for a pair of 8 selectable RF filter channels over a wide range of frequencies with Excellent stopband performance. Eight individual channels can be customized over a wide range of frequencies, typically over a 1 MHz to 2000 MHz range. Channels 1 through 8 are miniature Elliptical Lumped Element Bandpass Filters. This filter typology allows the 310-020008-001 to provide Superior close in stopband performance with exceptionally Low Insertion Loss. The filter bank is powered through a filtered 15 pin DSub connector that is mounted on one end of the unit. Pin 13 applies +5 V, pins 2, 9, and 10 provide TTL selection of the desired operating channel, and Pin 9 provides an additional BIT select. The additional BIT select provides the end user with the ability to apply a test sweep to the input of the filterbank and check the performance without having to remove the unit from an installation. The unit has 5 Frequency (MHz) Switching Speed Input 1 dB Comp.
