The 40W Threshold: Unleashing Industrial-Grade Power for the 3-4GHz Ecosystem
The 3-4GHz band is the workhorse of modern connectivity—powering 5G NR macro cells, long-range surveillance radars, and secure tactical data links. The ACASOM 40W 3-4GHz Broadband Amplifier pushes the boundaries of what’s possible in this critical spectrum. With a commanding 46dBm (40W) of saturated output power and 45% Gallium Nitride efficiency, this compact powerhouse delivers the link budget required for high-density urban deployments, extended-range telemetry, and resilient defense communications.
Engineered for the most demanding infrastructure projects, this amplifier provides the headroom to overcome path loss in challenging environments, penetrate reinforced structures, and maintain link integrity under adverse conditions. Housed in a ruggedized IP54 aluminum enclosure, it is designed for permanent installation in telecom shelters, mobile command vehicles, or exposed antenna towers.
Why This 40W Amplifier Sets the Standard for 3-4GHz Infrastructure:
Industrial-Grade 40W Output Power: Delivers a rock-solid 46dBm (40W) across the entire 3000-4000MHz range, providing the link margin needed for high-density small cells, macro cell backhauls, and long-range telemetry.
Advanced GaN-on-SiC Technology: Leverages state-of-the-art Gallium Nitride-on-Silicon Carbide (GaN-on-SiC) HEMTs to achieve ≥45% power-added efficiency, reducing operational costs and thermal management requirements in 24/7 deployment scenarios.
Broadband 3-4GHz Coverage: Optimized for the 3000-4000MHz spectrum, covering 3.3-3.8GHz 5G NR bands, 3.5GHz CBRS, 3.6-3.7GHz defense frequencies, and various radar and telemetry allocations.
High-Linearity 40dB Gain: A highly linear 40dB gain stage preserves complex waveforms (256-QAM, OFDMA, FMCW) with minimal EVM, ensuring spectral efficiency and data integrity.
Infrastructure-Grade Enclosure: Encased in a precision-machined aluminum chassis with IP54 ingress protection (dust and water splash resistant). Measuring just 132x53x17mm and weighing 210g, it withstands vibration, thermal cycling, and environmental exposure.
Universal Integration: Features SMA-K (female) RF connectors, heavy-duty AWG18 power leads, and a 3-28V TTL-level control line for remote enable/disable from network management systems or site controllers.
Extended Temperature Range: Certified for continuous operation from -30℃ to +85℃, ensuring reliable performance in outdoor enclosures, unventilated shelters, and extreme climates.

Recommended Cooling Solution (For Continuous 40W Operation):
To support continuous 24/7 operation, a robust thermal management solution is essential:
Heatsink Base: ≥ 15 mm thick aluminum or copper
Fin Array: ≥ 40 mm tall, optimized for natural or forced convection
Airflow: 30-50 CFM fan recommended for installations in enclosed spaces
Thermal Interface: High-performance thermal grease or phase-change pad
Critical Operational Notes:
Power Supply Requirement: Requires a stable, low-ripple 28V / 5A minimum DC power supply. For redundant or high-reliability installations, a 28V / 6A supply is recommended.
Thermal Management is MANDATORY: At 40W output, the amplifier must be attached to a suitable heatsink with active airflow for any duty cycle above 30%. Failure to do so will result in thermal shutdown or permanent damage.
Safe Power-Up Sequence: To ensure stable operation: (1) Connect RF Load/Antenna, (2) Apply 28V DC, (3) Apply RF Input. Reverse sequence on power-down.
Optimal Drive Level: For maximum linear output (46dBm), drive the amplifier with 6-8dBm input. The gain is 40dB, so 6dBm input yields 46dBm output. Do not exceed +10dBm input.
Remote Control Integration: The control line is active-high (3-28V). Leave floating or ground to disable. Compatible with 3.3V/5V logic for remote monitoring and control systems.
Primary Applications (3-4GHz):
5G NR Macro & Small Cells: Power 3.3-3.8GHz base stations for high-capacity urban and suburban coverage.
CBRS (Citizens Broadband Radio Service): Drive 3.5GHz radios for private LTE/5G networks in industrial IoT, smart factories, and enterprise campuses.
Defense & Tactical Communications: High-power amplification for tactical data links, UAV command-and-control, and forward-deployed sensor networks.
Surveillance & Weather Radar: Boost FMCW radar returns for air traffic control, weather monitoring, and border surveillance systems.
Satellite Communications (C-Band): Uplink power for 3.4-4.2GHz satellite terminals in flyaway, maritime, and fixed VSAT installations.
RF Component Testing: High-power stimulus for testing 3-4GHz filters, circulators, antennas, and high-power loads.
