Solid-state power amplifiers
Unprecedented reliability and linearity for the satcom industry
IRT SSPAs
Designed for mission-critical SATCOM applications
IRT solid-state power amplifiers (SSPA) offer unmatched reliability and linearity for SATCOM and military applications. Powered by advanced GaN technology, they deliver superior power density, efficiency, and up to 10x more output than GaAs HEMT, withstanding extreme conditions.
Equipped with SNMPv3 cybersecurity, IRT SSPAs ensure secure communications with authentication, encryption, and access control. Trusted by system vendors worldwide, our SSPA set the standard for high-performance, mission-critical amplification.

Key features
GaN Technology
• Solves the primary issues with High-Power Amplifier (HPA) technology: power density and power efficiency.
• New generation GaN technology exceeds the capabilities of traditional GaAs amplifiers, enabling them to reach the highest available power level with the best linearity on market.
• Can withstand 200°C junction temperature with resitance to solar radiation.
• Up to 10X more output power per unit compared to GaAs HEMT.
Cyber Security SNMPv3
• SNMPv3 is a protocol for managing and monitoring network devices. Key security features include authentication, privacy (encryption), and access control.
• “User-based” administration, allowing for more granular control over who can ensures data confidentiality.
• Prevents unauthorised access and ports authentication and encryption : SNMPv3 data cannot be read after capture. Only authorised users can access specific object identifiers.

FAQs
TWTAs use vacuum tube technology to amplify RF signals, providing high power, wide bandwidth, and efficiency at high frequencies. In contrast, SSPAs use semiconductor transistors, offering better reliability, compact size, and lower maintenance costs but generally lower power output.
IRT SSPAs can operate a wide frequency range, and can be used in various bands.
Unlike travelling wave tube amplifiers (TWTAs) which are sensitive to environmental conditions, our SSPAs can operate in the harshest conditions.
Our SSPAs are used for and not limited to VSAT, mobile satellite, and tactical communication systems.
Yes, in some systems, TWTAs and SSPAs can be combined to take advantage of the strengths of both technologies. For example, SSPAs may be used for lower power applications, while TWTAs handle high-power amplification.
