TELEDYNE DEFENCE LIMITED Switched Multiplexer Technical Data SA212-M1 A Teledyne Technologies Company Features Operating Range 2 – 6 GHz 16 Contiguous channels Low loss Low channel ripples Bandpass / Bandstop configuration Applications Adaptive filtering Interferer removal Channelisation Product Description The SA212-M1 Switched Multiplexer (SwMux) is a fast multi-configurable filter bank working in the 2GHz to 6 GHz frequency range. Consisting of 16 channels, each one independently controlled, providing over 65,500 combinations of overall filter responses capable of changing every 100nsecs to a different filter response. This provide the user with a fast, flexible, filter network capable of providing differing Band pass or Band stop responses on a pulse by pulse basis in dense signal environments. When used in conjunction with a DG009-M1 ADU, these components can provide the ability to detect interfering signals and remove them from receiver systems on an adaptive basis. The SwMux has a single RF input feeding a power splitter and in turn 16 independently controlled channels. The outputs of these channels are then recombined in a further power splitter providing a single RF output. Control of the SwMux is achieved by setting 16 control bits on the control port. Control data is not latched within the SwMux, allowing maximum user flexibility. The SwMux has been designed for use in airborne transport environments of –20 degC to +80 degC and up to 50,000 feet altitude Global Defence & Security Solutions SA212-M1 Rev 2.0 16 November 2009 Page 1 of 4 © Teledyne Defence Ltd, 2009.
