Product Description

When 20W-class UHF transmit stages no longer provide sufficient link margin, the next step is a higher-output module that maintains protection against real-world antenna conditions. The 700-830MHz 30W RF Power Amplifier delivers 45dBm single-direction transmit power with a circulator guarding the output stage against reflected energy. It is engineered for emergency communication systems, oil and gas pipeline telemetry, border surveillance networks, and long-range UAV command uplinks. The 24V 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

  • Emergency Communication Systems: Extend one-way transmit coverage for disaster response and public safety operations.
  • Oil & Gas Pipeline Telemetry: Boost transmit signals for remote pipeline monitoring and control.
  • Border Surveillance Networks: Enhance transmit links for remote surveillance and intrusion detection.
  • UAV Command Uplinks: Reinforce command signal strength for long-range drone missions.
  • Remote Industrial SCADA: Improve uplink signal strength for isolated industrial monitoring.
  • Licensed UHF Field Testing: Support higher-output experimentation and RF validation.

Key Advantages

30W-Class Output for Extended UHF Reach. This RF Power Amplifier provides 45dBm in a single-direction transmit path, adding substantial RF headroom for emergency communications, pipeline telemetry, and border surveillance links that require more reach than a 20W stage can deliver.

Circulator-Protected Output Stage. 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.

Compact 0.25Kg Chassis with 24V DC Input. The 128*53*17mm aluminum enclosure uses passive cooling, while the 24V DC input, 2.8A@24V current draw, and SMA female connector simplify integration into existing radio racks and portable systems.
