Typical Specifications
Description
Frequency (GHz)
Spectrum Microwave’s 310-020227-001 filterbank
provides five selectable RF filter channels over a
wide range of operation in a relatively small package.
One compact unit covers a wide range of
frequencies, typically 1 GHz to 3 GHz. Channels 1
through 5 are miniature lumped element bandpass
filters with electrical specifications completely
customizable by the end user. This relatively small
filter bank provides a minimum of 30 dB of isolation in
between non-selected passbands and 40 dB stop
bands.
The filter bank is powered by -5V and +5V DC
applied to external bias pins mounted on the end of
the unit. A grounding terminal is also provided. Three
control pins provide TTL selection of the desired
operating band. The unit is bi-directional with SMA
field removable connectors.
