New 70W DBS-band Outdoor, Mini Amplifier Joins Growing Family of Small, Lightweight Devices

Spacepath Communications (‘Spacepath’), a dedicated, European-based SATCOM high power amplifier (HPA) manufacturer is extending its range of small, lightweight amplifiers with the new STA 3407 ultralinear series.

On display for the first time, the compact STA 3407 is a 70W DBS-band (17.3-18.4 GHz) outdoor amplifier weighing just 9kg and featuring BUC and Ethernet options. This will be showcased in Amsterdam along with Spacepath’s range of HPAs introduced earlier this year, including:

STR Series Rack Mount Touch-Screen TWTA: Indoor rack-mount travelling wave tube amplifiers (TWTA) covering C-, X-, Ku- & DBS-band with an output power of 400, 500 and 750W. The 4U high amplifiers feature a touch-screen TFT front panel providing an easy-to-use visual interface for monitoring and controlling the amplifier. The panel displays the HPA’s operational status, including power output and temperature, graphical displays of parameter trend analysis and event logs. Local and remote diagnostics can also be easily performed via a built-in Ethernet network interface.

Ku-band Satellite Block Upconverter (SAT-BUC): The 150W BUC model is the smallest, lightest and most power efficient in its class. The amplifier is fitted with an L-band input and an auto-sense internal 10MHz source. It is available for immediate shipment in single thread and redundant systems.

STA 1341 Series: A 400W Ku-band antenna mounted, outdoor HPA weighing just 13.6kg. The amplifier has an integrated lineariser assembly and offers ultralinear performance in a small, lightweight and power-efficient package. It is fitted with Ethernet and a web browser capability. The amplifier can be provided in single thread and redundant configuration.

STA 3252 Series: A 500W Ka-band outdoor TWTA which is among the lightest in its class on the market, weighing only 18kg. The amplifier is offered in 27.5-30GHz and 30-31GHz bands and includes Ethernet/web browser and optional uplink power control. The HPAs incorporate a high efficiency, multi-collector TWT powered by an advanced power supply. Available in either an air- or liquid-cooled configuration, the amplifiers feature a compact form factor and resilient design enabling them to operate across a range of extreme environmental conditions. The HPAs also include a hub mounting for use with outdoor antennas. The amplifier can be provided in single thread and redundant configuration.

Newton Burnet, Director, Spacepath Communications said: “The launch of the new STA 3407 DBS amplifier bridges the gap between the low power solid state devices and the high power 500 & 750W amplifiers already in our product range. By combining this level of new product development with the proven performance of Stellar amplifiers, first-class customer support and a deep understanding of customer requirements in this market, Spacepath’s record of innovation as a European HPA manufacturer remains second to none.”

Spacepath Communications high performance uplink amplifiers cover all mission-critical segments including satellite newsgathering (DSNG), flyaway or truck-based systems, fixed earth stations and military satellite communications.
