2 - 18GHz Switch Multiplexer SA219 2 - 18GHz Switch Multiplexer The Switch Multiplexer is a single RF input to single RF output, fast, multi-configurable filter bank covering 2 - 18GHz. Filter control is achieved via Serial data lines on the VME backplane. Consisting of 16 channels (2 - 18GHz), these are equally spaced 1GHz channels. Each channel is independently controlled, allowing 65536 possible combinations of overall filter response from input to output. In addition 8 tap out ports, split into 2GHz wide bands, are provided for monitoring purposes should this be required. In normal operation these are terminated in 50 ohm loads. With internal amplification providing zero loss and low noise figure, together with flat insertion loss and exceptionally flat group delay, the filter is an ideal system enhancement. Designed to with stand harsh military environments, the SA219 is a complete front-end filter solution allowing system designers to achieve functionality previously unattainable. This provides the user with a fast, flexible, filter network capable of providing different band-pass or band-stop responses on a pulse-by-pulse basis in dense signal environments.
