RF Infrastructure for Satellite Ground Terminals

A ground terminal is where the satellite link meets the terrestrial network. From a rooftop VSAT to a gateway earth station, the RF chain between the antenna, the block converters and the modem runs on interfaces that have to stay stable through weather, wind and years of unattended service.

Design Notes

The Ground Terminal Signal Chain

Five points where the interconnect decides whether a terminal meets its link budget.

01
Feed to LNB
The lowest-noise part of the whole chain. Loss here is added directly to the system noise temperature, so it is the one place where a fraction of a decibel genuinely matters.
02
BUC Interface
On the transmit side the block up-converter runs at power. The interface has to handle it without generating intermodulation back into the receive band.
03
IF Run to the Modem
Often a long cable run indoors. Loss, screening and phase stability over that run set how much equalisation the modem has to do.
04
Outdoor Exposure
Antenna-mounted electronics sit in the weather with no enclosure to hide behind. Sealed interfaces and correct drip-looping are what keep water out of the chain.
05
Pointing Stability
Cable stiffness pulls on a small antenna. Flexible, correctly dressed assemblies keep the dish where it was aimed.

Our Role

What We Supply for Ground Terminals

01
Ka- and Ku-Band Interfaces
2.92mm and 2.4mm precision connectors that hold their match across the full Ka allocation, not just at the band centre.
02
Assemblies Made to the Run
IF and RF runs built to your actual lengths with the right jacket for the installation, so nothing is coiled behind the antenna.
03
Documented and Traceable
Measured data and material certificates with every assembly, which is what gateway operators ask for at acceptance.
