Switched Filter Bank Wide Band 5 Channel Filter Bank (1000 - 3000 MHz) Features • • • • • • • • Small Physical Package (<5.2 in3) High Power Handling >+25dBm Wide Band Operation High Speed < 395 nsec Low Video Feedthru <1.2 mV Low Insertion Loss <3 dB 50 dB Isolation Excellent IMD Suppression 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. Typ.
