[Satnews]  Stellar Satcom, a joint venture business formed by Spacepath Communications (‘Spacepath’), and Polarity Inc., will be launching an updated product portfolio at the 2016 NAB Show.

The new range includes rack-mounted touch-screen traveling wave tube amplifiers (TWTA); Ku- and Ka-band series ultra linear, high efficiency TWTAs and a lightweight SAT-BUC. Backed by Spacepath, the company behind the Stellar family of high power outdoor amplifiers, and Polarity Inc., Stellar Satcom’s combined wealth of industry experience will set the pace in high power satellite uplink performance for the fixed earth station and transportable satellite broadcast uplink markets.
 
The 2016 NAB Show product line-up will include:
 

• STR Series Rack Mount Touch-Screen TWTA: Indoor rack-mount traveling 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 to provide 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. 
• STA1341 Series: A new 400W Ku-band antenna mount, outdoor HPA incorporating a peak power TWT with an integrated lineariser assembly. The STA1341 amplifier offers ultralinear performance in a small, lightweight and power efficient package. It is fitted with Ethernet and web browser capability. The amplifier can be provided in single thread and redundant configuration.
• STA 3252 Series: A new 500W Ka-band outdoor TWTA, the lightest amplifier on the market, weighs only 18kg. The amplifier is offered in 27.5-30GHz and 30-31GHz bands and includes Ethernet/web browser and an optional uplink power control. The amplifier can be provided in single thread and redundant configuration.

Steve Ludvik, Director of Business Development, Stellar Satcom, said, “While exhibiting at the NAB Show for the time as a joint venture business, the Stellar range of products has a long-established and loyal following in North American. As Stellar Satcom, we now combine the proven performance of Stellar amplifiers with new product innovation, first-class customer support and a deep understanding of the demanding requirements for customers in this market.”
 
Applications for Stellar Satcom’s 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.
