C-Band Power in a Featherweight PCBA: 5W of GaN Efficiency for 3-4GHz Innovation

The 3-4GHz spectrum is the industrial backbone of modern wireless—powering 5G NR macro networks, CBRS private LTE, defense radar systems, and satellite communications. The ACASOM 5W 3-4GHz Broadband Amplifier PCBA delivers this critical frequency coverage in an ultralight package weighing just 8.7 grams. Pumping out a clean 37dBm (5W) of RF power with 45% GaN efficiency, this bare-board module is purpose-built for integrators, researchers, and developers who need professional-grade C-Band amplification without the weight penalty.

Engineered for 5G small cell development, CBRS radio prototyping, radar test benches, and embedded defense applications, this amplifier slips into tight enclosures and custom builds—delivering laboratory-grade performance in a featherweight form factor.

Why This 5W 3-4GHz PCBA Amplifier is Essential for C-Band Innovation:

Optimized for 3-4GHz Spectrum: Specifically engineered for the 3000-4000MHz range—covering 3.3-3.8GHz 5G NR bands, 3.5GHz CBRS, 3.6-3.7GHz defense allocations, C-Band satellite uplinks, and radar frequencies.
Incredible Power-to-Weight Ratio: Delivers 5W (37dBm) of clean output while weighing only 8.7g—ideal for UAV-mounted spectrum monitoring, portable test equipment, and weight-sensitive prototypes.
High-Efficiency GaN Technology: Achieves ≥45% power efficiency at full output using advanced Gallium Nitride devices, meaning less heat generation and lower current draw from your power source.
Powerful 35dB Gain: A robust 35dB gain stage ensures your existing signal is boosted to maximum power with minimal added noise, preserving critical modulation integrity.
Ultra-Compact PCBA Form Factor: Measures just 69x38x4mm—easily integrates into tight spaces, ideal for embedded systems, lab prototypes, and custom RF assemblies.
Wide Voltage Compatibility: Accepts 22-28V DC input with a dedicated control line (3-32V) for remote on/off switching from microcontrollers or control systems.
Premium Components: Built with high-reliability, military-grade components for consistent performance across extended temperature ranges (-30℃ to +85℃).

Critical Usage Notes:

Power Supply Requirement: Use a stable 24V / 1A minimum DC power supply. For best results, a 24V / 1.5A supply is recommended for headroom.
Thermal Management: At full 5W output, adequate heat dissipation is recommended. In enclosed spaces or continuous operation, consider a small heatsink or ensure passive airflow.
Safe Connection Sequence: Always connect the antenna FIRST, then apply DC power, and finally enable your RF source.
Optimal Input Drive: For maximum clean output (up to 37dBm), provide an input signal of 3-4dBm (accounting for the 35dB gain). Avoid overdriving the input beyond +10dBm.
Control Line Function: The control line (3-32V) enables remote on/off switching—ideal for microcontroller integration or automated test systems.
PCBA Handling: This is a bare-board module. Ensure proper insulation, secure mounting, and RF grounding for optimal performance.
