4000-5000MHz 50W GaN Broadband Power Amplifier for C-Band, Satellite & 5G Communications – 47dBm Output
Product Description
The 4000-5000MHz C-band serves as a critical spectrum for satellite communications (SATCOM) , 5G infrastructure, weather radar systems, point-to-point microwave links, and aerospace telemetry—applications that demand consistent high-power performance across a wide frequency range. This 4000-5000MHz 50W GaN Broadband Power Amplifier delivers a robust 47dBm (50W) of clean output power with 40dB gain across the full 4000-5000MHz spectrum, covering C-band satellite downlinks and uplinks, 5G mid-band frequencies, and radar systems. Leveraging advanced GaN (Gallium Nitride) technology for superior efficiency, linearity, and thermal performance, it operates on a 28V DC supply with just 3.8A current draw at full output. Housed in a rugged aluminum enclosure with SMA-K connectors and built-in power control, it's engineered for satellite operators, telecom engineers, and system integrators who need wideband flexibility and the ultimate high-power performance across the C-band spectrum.

Key Advantages
With 50W (47dBm) of clean GaN-powered output across the 4000-5000MHz C-band, this amplifier delivers 6-10× the effective range of standard 1W transmitters, covering satellite communications, 5G infrastructure, weather radar, and point-to-point backhaul in a single wideband solution. The 40dB gain ensures consistent, predictable linearity even from low-power exciters, while the efficient 3.8A 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 satellite terminals, radar systems, or telecom networks. The 28V operating voltage ensures compatibility with aircraft 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 4000-5000MHz C-band, this amplifier covers critical frequencies used by satellite ground stations, 5G mid-band networks, weather radar systems, and aerospace telemetry. Whether deployed in ground stations, radar installations, or UAV platforms, it delivers the wideband flexibility and ultimate power that mission-critical C-band applications demand.
