Spread spectrum high bit rate satellite links

AMS has been involved in the design of a VSAT (Very Small Aperture Terminal) for satellite communications in the Ku band. Specifically AMS has been contributed to the RF front-end design of the ground terminal. The terminal can support high bit rates of communication up to 2Mb/s. Spread spectrum techniques have also been employed in order to support secure and jamming resistive communications.

The RF front end is comprised from a very low noise amplifier (NF<1dB), a linear power amplifier (Pout>8Watts), a PLL sub-system and frequency converters for the uplink and downlink.

Custom VSAT Ku band DS-Spread Spectrum 2Mb/s RF front-end.

Extensive use of multilayered printed circuit board hybrid low cost technology.

Used for both civilian and military communication links.

Potential upgrade to higher bit rates.
