700-830MHz 40W RF Power Amplifier with Circulator – High-Power UHF Transmit Stage for Critical Infrastructure, Railroad Telemetry & Emergency Response Radio

Product Description

When UHF transmit links support critical infrastructure, railroad telemetry, or emergency response radio, link failure is not an option. This 700-830MHz 40W RF Power Amplifier delivers 46dBm single-direction transmit power with a circulator guarding the output stage against antenna mismatch and reflected energy. It is engineered for utility network control, rail signaling and tracking, pipeline monitoring, and first-responder communications. 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 where high output and output protection are both required.

Typical Applications

• Critical Infrastructure Communications: Extend one-way transmit coverage for utility, water, and energy network control.
• Railroad & Transport Telemetry: Reinforce transmit links for rail signaling, tracking, and wayside monitoring.
• Oil & Gas Pipeline Monitoring: Boost transmit signals for remote pipeline sensors and leak detection systems.
• Emergency Response Radio: Improve transmit coverage for disaster recovery and first-responder communications.
• Remote Utility SCADA Uplinks: Increase link margin for isolated grid monitoring and control points.
• Licensed UHF Field Testing: Support higher-output experimentation and RF validation.

Technical Specifications

Key Advantages

Circulator-Protected Output for Critical Links. The circulator provides output isolation and VSWR protection, reducing the risk of PA damage from antenna mismatch and reflected power in field installations where environmental and antenna conditions change.

46dBm Transmit Output in a 0.25Kg Chassis. This RF Power Amplifier delivers 40W(46dBm) in a single-direction transmit path, adding substantial UHF link margin for critical infrastructure, railroad telemetry, and emergency response radio without increasing equipment footprint.

28V DC and SMA Female Field Integration. The 28V DC input, 3.2A@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.
