The 350-02874-0001 from Lexatys is an Amplified Switch Filter Bank that operates from DC to 8000 MHz. It consists of an amplifier, 8 filtered channels, a bypass channel, and a default safety load channel. Each of the 8 channels and the bypass channel can be selected to have a through-path, an amplified path, or an attenuated path which can be enabled as desired. The Switch Filter Bank uses MEMS-based switching to provide minimal delay as inputs are shunted to the load before channel settings are changed. Each channel can handle up to 30 dBm of power.
The amplifier has an output P1dB of over -5 dBm (active mode), 27 dBm (passive mode) with a selectable gain of 10 dB. The filter bank is designed utilizing a spread spectrum clock that allows limiting spurious emissions below -100 dBm.
The 350-02874-0001 can also be stacked with higher frequency banks to cater to a broader range without compromising useful space. The channel selection is controlled via a GUI or CLI interface, and power and data connections are provided via a single USB-C plug. This USB-Powered filter bank is available in a module that measures 3.0 x 5.0 x 0.5 Inches.
