Command the C-Band: 20W of Clean Power for Critical 3-4GHz Applications
The 3-4GHz spectrum is home to some of the most demanding RF applications—from radar systems and satellite communications to industrial telemetry and advanced drone links. The ACASOM 20W 3-4GHz Broadband Amplifier is engineered to deliver the power, efficiency, and reliability these mission-critical operations demand. With a massive 43dBm (20W) of clean RF output across the entire 3000-4000MHz range, this rugged, ready-to-mount amplifier ensures your signals penetrate interference, overcome distance, and maintain integrity in the most challenging environments.
Whether you're deploying C-Band communication links, boosting radar test signals, or powering specialized UAV operations, this amplifier delivers uncompromising performance in a compact, field-ready package.
Why This 20W 3-4GHz Amplifier Dominates:
Massive 20W Output Power: Delivers a clean 43dBm (20W) of RF power specifically optimized for the 3-4GHz band, providing exceptional link margin and penetration through obstacles.
Optimized 3-4GHz Coverage: Engineered specifically for the 3000-4000MHz spectrum—covering C-Band communications, radar systems, 3.5GHz CBRS, 3.6-3.8GHz fixed wireless, and industrial telemetry applications.
High-Efficiency GaN Technology: Achieves ≥45% power efficiency at full output using advanced Gallium Nitride (GaN) devices, meaning less heat generation and lower current draw from your power source.
Powerful 40dB Gain: A robust 40dB gain stage ensures your existing signal is boosted to maximum power with minimal added noise, preserving critical signal integrity.
Rugged Aluminum Enclosure: Housed in a precision aluminum chassis measuring 132x53x17mm and weighing only 210g—provides excellent RF shielding, physical protection, and passive heat dissipation.
Ready-to-Use Connectors: Features SMA-K (female) RF connectors on input and output, plus AWG18 20cm red/black power wires for easy integration.
Remote Control Capability: Dedicated 3-24V 20cm red control wire for remote on/off switching from your control system.
Field-Ready Design: Built to operate reliably from -30℃ to +85℃, ready for the most demanding environments.

Recommended Heatsink Dimensions:
For sustained full-power operation in high-temperature environments, we recommend adding a heatsink with the following minimum dimensions:
Base Thickness: ≥ 8mm
Fin Height: ≥ 25mm
Overall Footprint: Slightly larger than amplifier base (132x53mm)
Critical Usage Notes:
Power Supply Requirement: Use a stable 24V / 3A minimum DC power supply. For best results, a 24V / 4A supply is recommended for headroom at 20W output.
Thermal Management is ESSENTIAL: At full 20W output, the aluminum enclosure provides basic passive cooling. For continuous operation or high-ambient environments, active cooling with a heatsink and fan is strongly recommended.
Safe Connection Sequence: Always connect the antenna FIRST to the SMA output, then apply DC power, and finally enable your RF source.
Optimal Input Drive: For maximum clean output (up to 43dBm), provide an input signal of 3-4dBm (accounting for the 40dB gain). Avoid overdriving the input beyond +10dBm.
Control Line Function: The red control wire (3-24V) enables remote on/off switching—ideal for integration with control systems or power management.
Mounting: The aluminum enclosure provides multiple mounting options. Ensure secure attachment in vibration-prone environments.
