Product Description
The 100-400MHz spectrum spans critical communication bands used in VHF aviation (118-137MHz) , marine radio, public safety networks, military tactical communications, amateur radio (6m/2m bands) , and SCADA telemetry. This 100-400MHz 30W GaN Broadband Power Amplifier delivers a robust 45dBm (30W) of clean output power with 40dB gain across the full 100-400MHz range, providing consistent high-power performance across VHF and UHF frequencies in a single compact unit. Leveraging advanced GaN (Gallium Nitride) technology for superior efficiency, linearity, and thermal performance, it operates on a 28V DC supply with just 2.4A current draw at full output. Housed in a rugged aluminum enclosure with SMA-K connectors and built-in power control, it's engineered for professionals who need reliable, wideband amplification across the most critical communication bands.
Typical Applications
- VHF Aviation Communications (118-137MHz): Amplify ground-to-air and air-to-ground communication links
- Public Safety & Emergency Services: Boost police, fire, and EMS radio networks in VHF/UHF bands
- Military Tactical Communications: Wideband amplification for field-deployed communication equipment
- Marine & Maritime Communications: Enhance ship-to-shore and vessel-to-vessel radio links
- Amateur Radio (HAM) 6m & 2m Bands: High-power linear amplification for VHF operations
- SCADA & Industrial Telemetry: Extend range for remote monitoring and control systems

Key Advantages
With 30W (45dBm) of clean GaN-powered output across the 100-400MHz spectrum, this amplifier delivers 6-10× the effective range of standard 1W transceivers, covering VHF aviation, public safety, military tactical, and marine communications in a single wideband solution. The 40dB gain ensures consistent, predictable linearity even from low-power exciters, while the efficient 2.4A current draw and 210g compact design make it ideal for both fixed infrastructure and mobile field deployment.
Built-in remote power control via the 3-28V red wire allows dynamic output adjustment—perfect for real-time power management in base stations, vehicle-mounted systems, or portable field kits. The 28V operating voltage ensures compatibility with vehicle electrical systems, battery banks, and regulated power supplies, while SMA-K connectors enable plug-and-play integration with existing RF chains.
Precision-tuned for the 100-400MHz range, this amplifier covers critical frequencies used in aviation communications, public safety networks, military tactical radios, marine systems, and amateur radio. Whether deployed in control towers, emergency response vehicles, ships, or field command posts, it delivers the wideband flexibility and reliable power that VHF/UHF communication systems demand.
