Spacepath Extends Outdoor Amplifier Range With Compact, 1.5 Kw C-Band GaN BUC/SSPA

SpacePath Communications, a division of ETL Systems, that provides high-performance satellite uplink amplifiers for the global SATCOM market, has introduced its highest power stand-alone C-band BUC/SSPA utilizing the latest Gallium Nitride (GaN) technology.

The powerful outdoor SSPA is suited for replacing aging indoor TWTAs, enabling service providers to eliminate long waveguide runs by installing high-power amplifiers closer to the antenna. The solid-state amplifier’s compact size and power capacity make it ideal for operators to free up valuable indoor rack space. An indoor rack mount version is also available that is only 8RU high, making this device significantly smaller than older generations of TWTA.

The GaN BUC/SSPA delivers 1.5 kW Psat within a small form factor, weighing just 56kg, and boasts high thermal efficiency with a mean time between failure (MTBF) rating designed for mission-critical applications, where reliability is essential. Additional features include best-in-class RF performance, RF sample port, true RMS power measurements, and flexible monitor/control capabilities.

Colin Bolton, director of business development, SpacePath Communications, said, “The 1.5 kW amplifier enables operators to replace their indoor amplifiers and benefit from the high power and performance of solid-state technology while saving significant prime power and freeing up space. The reliability of GaN-based amplifiers also delivers a lifetime of exceptional performance, together with lower capital and operating expense.”
