2-18GHz 100W High-Power Amplifier Modules and Standard Rack System

KeyLink's portfolio of high-power amplifiers in the 2-18GHz band—the KB20180M50AV high-power amplifier module and KB20180S50A high-power amplifier system—offers users a complete selection, from highly integrated modules to plug-and-play standard rack systems, all centered around a unified 100W output power and 50dB gain.

KB20180M50AV (Amplifier Module): A compact, standalone amplifier module measuring 360x370x100 mm and powered by 28V DC. It is designed for users requiring high integration of high-power amplification capabilities into custom devices, drone platforms, automotive systems, or dedicated chassis. This module is a core cornerstone for building dedicated RF systems.

KB20180S50A (Amplifier System): A complete, all-in-one standard rack-mount device in a 19-inch, 5U+2U industrial standard chassis, supporting a wide AC power range of 100~260VAC. This system integrates power supply, control, and protection circuitry, allowing for quick and easy integration into existing test benches or equipment racks. It is an ideal ready-to-use solution for laboratory testing, fixed-station communication, and EMC testing applications. 

Key Advantages:

1. Ultra-wideband high-power performance: Provides a stable 100W saturated output power and 50dB high gain across an ultra-wide bandwidth from 2GHz to 18GHz. Instantaneous bandwidth covers multiple key bands including S, C, X, and Ku, meeting the demands of frequency agility and wideband signal processing.

2. Advanced semiconductor technology: Built with advanced power devices such as GaN (Gallium Nitride), GaAs, and LDMOS, and MMIC technology, it achieves an optimal balance between high efficiency, high linearity, and high reliability, making it particularly suitable for long-term full-load operation.

3. Comprehensive Monitoring and Protection (Key Advantages of the KB20180S50A System): The rack system features built-in intelligent monitoring circuitry, effectively protecting against overdrive, load mismatch, and thermal overload faults, ensuring the safety of equipment and backend systems. It also provides Ethernet and RS232/RS422 digital interfaces, supporting remote power on/off, power level adjustment, and status monitoring, facilitating integration with automated systems.

4. Flexible Power Supply and Deployment: Users can flexibly choose between DC modules and AC rack systems based on site power supply conditions and installation space, greatly simplifying the complexity of engineering deployment.

Typical Applications： 

1. Radar and Electronic Warfare Systems: Serves as a broadband power source for generating interference signals in the driver stage of active phased array radar T/R components or electronic countermeasures systems.

2. Satellite and Microwave Communication: Provides high-purity power amplification for ground station uplinks or broadband microwave relays.

3. EMC Testing and Laboratory Measurement: Serves as a power amplifier source in electromagnetic compatibility testing, or is used to extend the output power of vector network analyzers and signal generators for high-power device testing.

4. TWT (Traveling Wave Tube) Amplifier Replacement: With its high reliability, long lifespan, and improved ease of use, KeyLink has become the solid-state upgrade option for traditional TWT amplifiers in many applications.
