TranSystem Inc., a world wide leader in MMDS/MDS
technology, offers a complete line of PCS, WCS and radar filtering downconverters. Our designs have been copeid by many, but the original out performs the rest. The digital ready AIDC easily integrates with parabolic antennas or any of our esthetically correct antennas.

TranSystem Inc., has been designing and manufacturing MMDS down converter since 1992.With a solid design and outstanding workmanship, we are able to sell into the most demanding markets such as the USA and Brazil with at least a hundred thousand units per year. Product performance, good product value, and in-time customer service are the important elements for such success. As we have claimed our product features as below, we invite you to test and see the performance yourself.
Features
  • The industry's first manufacturer to filter out PCS and WCS interferences.
  • Digital ready meets 256 QAM standard for future expansion.
  • Variable gain (18, 30, and 37 dB), different LO (2278 MHz or customized), and integrated antennas (12 dBi Corner Reflector, 15 dBi Spotbeam Dome, or 18 dBi Viper Yagi element antenna or 18/24 dBi grid antennas) options.
  • Lowest noise figures 1.5 dB max.
  • 100% environmental protection with weather protected featuring temperature range from -40¢XC to 70¢XC, humidity at 0 to 100%, leakage testing prior to shipment, and protection from lightning and surge.
  • Good input VSWR @ 1.2:1.
  • High Image rejection (>80 dB) and IF rejection (>80 dB).
  • Radar filter included.
  • NTSC, PAL, and SECAM compatible.
