700-830MHz 50W RF Power Amplifier with Circulator – 47dBm UHF Transmit Stage for Rail Communications, Emergency Response Networks & Industrial Microwave Links
Product Description
When UHF transmit links support rail communications, emergency response networks, or industrial microwave paths, a 40W stage may no longer provide sufficient link margin. This 700-830MHz 50W RF Power Amplifier delivers 47dBm single-direction output with a circulator at the output stage, protecting the PA against antenna mismatch and reflected energy. It is engineered for rail signaling and wayside monitoring, disaster recovery communications, industrial microwave relay, and remote utility SCADA uplinks. The 28V DC input, SMA female connector, and 15CM Red/Black Wire simplify integration into existing radio installations. Its 128*53*17mm aluminum housing weighs only 0.25Kg and uses passive cooling, making it suitable for pole-mounted, vehicle, and portable field deployments.
Typical Applications
- Rail & Transport Communications: Reinforce one-way transmit links for rail signaling, tracking, and wayside monitoring.
- Emergency Response Networks: Improve transmit coverage for disaster recovery and first-responder radio systems.
- Industrial Microwave Links: Boost transmit signals for point-to-point industrial microwave relay.
- Remote Utility SCADA Uplinks: Increase link margin for isolated grid monitoring and control points.
- UAV Command Uplinks: Extend command signal strength for long-range drone missions.
- Licensed UHF Field Testing: Support higher-output experimentation and RF validation.

Key Advantages
Circulator Protection for Field-Deployed UHF Links. The circulator provides output isolation and VSWR protection, reducing the risk of PA damage from antenna mismatch and reflected power in rail, emergency response, and industrial installations.
47dBm Output in a Compact 0.25Kg Chassis. This RF Power Amplifier delivers 50W(47dBm) in a single-direction transmit path, adding substantial UHF link margin for demanding rail, emergency, and industrial microwave applications without increasing equipment footprint.
28V DC and SMA Female Integration. The 28V DC input, 3.6A@28V current draw, SMA female connector, and 15CM Red/Black Wire simplify integration into existing radio racks and portable systems, while the 128*53*17mm aluminum housing provides passive cooling and mechanical protection.
