B5 850MHz 50 Watts Multi Carrier Solid State Power Amplifier
The EMTS Telecom Services PA-850-47W50 RF Power Amplifier is a high performance, high linearity solid-state amplifier specifically designed for professional wireless communication systems operating in the 850 MHz frequency band. The amplifier is optimized for 4G LTE, Private LTE, legacy GSM, UMTS/WCDMA, and other narrowband or broadband wireless applications requiring outstanding linearity, spectral purity, and long-term operational reliability.
Designed to support both single-carrier and multi-carrier operation, the PA delivers up to 50 W average linear RF output power while maintaining excellent adjacent channel performance, low intermodulation distortion, superior Error Vector Magnitude (EVM), and outstanding Adjacent Channel Leakage Ratio (ACLR), making it suitable for demanding commercial, industrial, public safety, and mission-critical communications systems.
The amplifier utilizes the latest generation of high efficiency LDMOS RF power transistors combined with advanced broadband matching networks and optimized RF combining techniques. Its Doherty amplifier architecture maximizes efficiency while maintaining exceptional linearity over a wide output power range, significantly reducing power consumption and thermal dissipation.
To ensure superior RF performance under continuous 24/7 operation, the PA incorporates advanced linearization techniques, high quality EMI/RFI suppression filters, precision machined aluminum housing for excellent thermal management, integrated protection circuitry, and carefully selected industrial-grade components. The result is outstanding gain stability, excellent phase and group delay characteristics, low distortion, high reliability, and long operational lifetime, even in harsh environmental conditions.
The compact, rugged design makes the PA an ideal building block for a wide range of applications, including:
• Cellular Repeaters (BDA) • Distributed Antenna Systems (DAS) • Private LTE Networks • Critical Communications Networks • Public Safety Infrastructure • OEM Wireless Equipment • RF Coverage Enhancement Systems • Industrial Wireless Applications
The PA-850-47W50 is designed for seamless integration into both new and existing wireless infrastructures and is available in customized frequency ranges, output power levels, and mechanical configurations to meet specific customer requirements.
