KeyLink's Full Range of L-Band Power Amplifiers Covering Applications from 20W to 200W

KeyLink, a leading RF technology company, offers four core products in its L-band power amplifier series: KB1017M43A (20W), KB1020M47A (50W), KB1020M50A (100W), and KB1020M53A (200W). This complete power matrix marks a key step forward for KeyLink in providing high-performance RF power solutions for global communication, radar, and electronic warfare systems.

 Developed on a unified L-band (1-2GHz) platform, this series meets the needs of different application scenarios through precise power grading:

1. KB1017M43A (1-1.7GHz, 20W): Designed for size and power consumption-sensitive applications, suitable for portable communication devices and test instruments, providing a stable 20W output in the 1-1.7GHz band.
2. KB1020M47A (1-2GHz, 50W): Balances compact design with high performance, measuring only 150×90×25 mm, suitable for space-constrained mobile platforms and system front-end drive stages.
3. KB1020M50A (1-2GHz, 100W): Provides reliable power for fixed-station communication and medium-sized radar systems, featuring an efficient heat dissipation design to support prolonged full-load operation.
4. KB1020M53A (1-2GHz, 200W): Offers maximum output power, designed specifically for long-range jamming and large radar systems, supporting stable operation under high-load tasks

The entire product series utilizes advanced GaN and LDMOS technologies, based on a solid-state power amplifier (SSPA) design, exhibiting several superior characteristics:

• Wideband Coverage: Supports full-band operation from 1-2 GHz, compatible with mainstream communication and radar frequencies.
• High Power Density: Achieves maximum power output within a compact size through optimized circuit layout and thermal management.
• High Reliability: Built-in over-temperature, over-current, and VSWR protection mechanisms, adaptable to harsh operating environments.
• Excellent gain flatness: Ensures uniform and stable signal amplification across the entire frequency band.

Typical Applications:

• Radar Systems: Provides high-power drive for ground stations and shipborne radar.
• Satellite Communication Uplink: Ensures stable signal transmission over long distances.
• Test & Measurement and Scientific Equipment: Provides instruments with a clean, high-power signal source.
• Electronic Countermeasures Systems: Wide bandwidth supports rapid frequency switching and jamming. 

This product series is in mass production, with ample stock for fast delivery. Detailed technical documentation, test reports, and sample support are available. KeyLink's technical team can also provide customized services based on customer needs.
