Double D Electronics Ltd designs and manufactures redundancy, switching and RF subsystems for use in Satellite Earth Stations and mobile applications. Augmenting standard products, a wide range of standard hardware and software modules enable configuration of dedicated solutions at reasonable cost. New product introductions all include network interface and browser/SNMP support.
Redundancy Controllers - for Waveguide Switching Systems, Modem or Up/Down Converter clusters, audio and video encoders and decoders, LNAs, LNBs, IRDs, TWTAs, KPAs. Optional transfer of failed path settings to standby during automatic switching. In particular, the DDA89 redundancy switch operates with many industry-standard up/down converters and modems, and the DDA86 and DDA286 are market-leading solutions for waveguide systems. New this year are the DDA289 redundancy switch with colour TFT, and the DDA282 general-purpose 2U redundancy controller with optional LNA/LNB/LNC.
RF subsystems - switching, combining, splitting, amplifying, level monitoring systems.
Alarm Units - collect equipment alarms and provide local indication, annunciation and acknowledgement. New this year is the DDA276 Alarm Unit, with 16 inputs, RS-485 and network/SNMP interface to RC&M systems. Fully configurable. IF/L-Band signal level monitors from -50dBm up.
Interface units for RC&M systems - protocol converters, analogue and digital I/O and similar units, with serial and network interfaces.
