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.

Increasingly powerful outdoor SSPAs are steadily replacing 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 makes it ideal for operators to free-up valuable indoor rack space. Applications include mobile broadcast, DSNG, VSAT, and fixed medium-large earth stations.

FAQs

What are the main differences between TWTAs and SSPAs?

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.

What are the frequency capabilities of SSPAs?

IRT SSPAs can operate a wide frequency range, and can be used in various bands.

How does the environment affect the robustness of SSPAs?

Unlike travelling wave tube amplifiers (TWTAs) which are sensitive to environmental conditions, our SSPAs can operate in the harshest conditions.

Which applications are SSPAs best suited to?

Our SSPAs are used for and not limited to VSAT, mobile satellite, and tactical communication systems.

Can TWTAs and SSPAs be used together?

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.
