Celestia TTi brings unique GaN based SSPAs in DBS band to broadcast satcom

22nd May 2024

Satellite operators running large teleport operations and satellite broadcasters seeking the ultimate technology to power their businesses now have a range of options to choose from thanks to a new generation of GaN SSPAs in DBS introduced to the market by Celestia TTi.

A specialist in delivering high performance SSPAs and BUCs with over 25 years’ experience under its belt, Celestia TTi has developed a line-up of high power SSPAs which rely on the latest solid state Gallium Nitride (GaN) technology to deliver outstanding solutions to broadcast satcom.

By using advanced GaN technology, the only company which offers GaN solutions at DBS frequency band, Celestia TTi is able to provide powerful, flexible and durable SSPAs that maximise linear power and are capable of operating seamlessly 24/7 in the most demanding environmental conditions. They also have a lifespan that far exceeds that of more traditional solutions on the market.

Simple to operate and maintain, Celestia TTi’s SSPA and BUC DBS product family of 200W, 300W and 550W models can deliver up to 54.8 dBm/57.4dBm/52dBm at P LINEAR from a highly compact footprint.

Its 200W SSPA/BUC delivers up to 52dBm at P LINEAR from a robust, ultra-compact unit.  Lightweight and with a small footprint, it offers high output power and outstanding performance at an extremely competitive price when the amplifier has to be located really close to the antenna, either at the antenna hub or arm. The 300W and 550W models simply offer exceptional performance combined with extremely high output power.

Celestia TTi’s GaN high power SSPAs offer a number of other benefits, including multi-carrier uplinks, with no limit in the number of carriers and separation of frequency among them, and less back off than older technologies such as TWTs.

The combination in phase of individual SSPA stand-alone modules allows outstanding output to be achieved for the entire product family of 1kW, 2kW and 3.5kW output powers. Soft-fail redundancy allows the system to operate even when an individual SSPA module fails, whilst hot swappable SSPA modules and field removable power supplies guarantee reduced maintenance and repair costs with minimal operational disruption.

The range also offers significant savings in operational costs, for instance by lowering electricity usage by up to 50% from multicarrier high-power uplinks, and in capital investment by reducing the number of antennas and associated footprint required.

“This new generation of super high power DBS band SSPAs based on GaN technology for broadcast and satcom is one of a kind on the market, offering a multitude of benefits for operators,” says Óscar Gago, Business Developer at Celestia TTi.

“Exceptional performance, combined with reliability and a keen eye on cost reduction, make our SSPA and BUC range a very attractive and competitive solution for broadcast in DBS band. With superior functionality and robust operation even in the most challenging settings, our products are the ultimate technology choice, giving satellite broadcasters and teleport operators all the power they need,” he says.

In addition to DBS band products, Celestia TTi also supplies a wide range of cost-effective SSPA solutions from a few watts up to kWs at a variety of frequency bands including C, X, Ku, K, Ka and Q/V bands.
