Switched Filter Banks
RF/ IF Pre-selectors to 18 GHz
(Passbands 1 - 2000 MHz; Stopband to 18 GHz)
Description
Spectrum Microwave’s 310-020226-001 filter-banks
provide two selectable RF filter channels over a wide
range of frequencies with ultimate rejections
requirements out to 18 GHz.
Two individual channels can be customized over a
wide range of frequencies, typically 1 MHz to 2000
MHz. Channels 1 and 2 are miniature Lumped
Element Bandpass Filters. This relatively small
filterbank provides excellent Passband performance
while suppressing ultimate rejections by >50 dB out
to 18 GHz.
The filter bank is powered by +5V DC applied to an
external bias pin mounted on the side of the unit. A
grounding terminal is also provided. One control pin
provides TTL selection of the desired operating
channel. The unit is bi-directional with SMA field
removable connectors.
Dimensions and Connections
3.50” L x 1.10” W x 0.45” H excluding SMA
connectors and control pins.
The chassis is machined aluminum with a silver plate
finish. Control pins are .030” dia.
