TELEDYNE DEFENCE LIMITED 0.5 – 18GHz Switch Multiplexer Technical Datasheet SA004 A Teledyne Technologies Company Features Full 0.5 – 18GHz 17 Channels Low Noise Figure Applications Broadband EW Signal Limiting Adaptive Filtering RWR System Protection Test Lab Filtering Product Description The Switch Multiplexer is a single RF input to single RF output, fast, multi-configurable filter bank covering 0.5 18GHz. Consisting of 17 channels (0.5 - 18GHz), these are equally spaced 1GHz channels. Each channel is independently controlled, allowing 131072 possible combinations of overall filter response from input to output. In addition 9 tap out ports, split into 2GHz wide bands, are provided for monitoring purposes should this be required. In normal operation these are terminated in 50ohm loads. 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. Filter control is achieved by 17 bit parallel low voltage TTL on VME control bits. 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 SA004 is a complete front-end filter solution allowing system designers to achieve functionality previously unattainable.
