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.
