In wireless communication systems, the RF power amplifier (PA) plays a crucial role—it amplifies weak RF signals to a sufficient power level to overcome transmission losses, ensure signal coverage, and guarantee communication reliability and stability. In short, the performance of the RF power amplifier directly determines the coverage, signal quality, and energy efficiency of the communication system.

Coreal specializes in RF power amplifier technology, offering products covering a wide frequency band from DC to 50 GHz with output power up to 5,000W. Utilizing a full range of LDMOS/GaAs/GaN process platforms, Coreal provides reliable power amplifier modules and customized solutions for communication systems of different architectures and frequency bands.

1. Mobile Communication Base Stations

• 5G Macro Base Stations: 5G macro base station power amplifiers typically require output power of 40W or more, and in some scenarios, even 60W or higher.
• 5G Small Cells and Future 6G Micro Cells: Unlike macro base stations, small cells and future 6G micro base stations are mainly deployed indoors and in hotspot areas, with a smaller coverage radius.

2. Satellite Communication: Amplifying signals in satellite transmission and reception systems.

3. Point-to-Point Microwave and Wireless Backhaul: Point-to-point microwave transmission is used for wireless backhaul links between base stations or between a base station and the core network, requiring power amplifiers with high output power and good phase noise characteristics.

4. Internet of Things (IoT) and Low-Power Wide Area Networks (LPWANs): In IoT and LPWAN scenarios, power amplifiers help improve link budget and expand coverage. While the power requirements of individual devices are not high, the massive number of connections poses challenges to the cost and integration of power amplifiers.

With the development of 5G and future 6G technologies, power amplifiers are evolving towards miniaturization and high integration. Coreal's over 1100 square meter Class 10,000 cleanroom and complete microelectronic packaging production lines (sintering, bonding, wire bonding, eutectic bonding, laser encapsulation) provide a solid manufacturing guarantee for high-reliability, high-consistency power amplifier modules.

Whether you are deploying 5G base stations, building satellite ground stations, or developing next-generation communication systems, Coreal can provide you with reliable products and technical support, from standard power amplifier modules to fully customized solutions.
