The 50W Benchmark: Absolute Power for the 3-4GHz Critical Infrastructure

The 3-4GHz spectrum is the backbone of national infrastructure—powering 5G NR macro networks, long-range air defense radars, and strategic satellite communications. The ACASOM 50W 3-4GHz Broadband Amplifier establishes a new benchmark for power density and reliability in this mission-critical band. Delivering a staggering 47dBm (50W) of saturated output power with 45% Gallium Nitride efficiency, this flagship amplifier provides the link budget to overcome the most challenging path losses, penetrate reinforced structures, and ensure uninterrupted connectivity in the most demanding environments.

Engineered for nationwide 5G deployments, strategic defense installations, and high-availability satellite ground stations, this amplifier represents the absolute pinnacle of solid-state power amplification in the 3-4GHz spectrum. Housed in a military-grade IP54 aluminum enclosure, it is battle-tested for continuous operation in the harshest field conditions—from exposed tower mounts to mobile command vehicles and remote radar sites.

Why This 50W Flagship Amplifier Sets the Standard for 3-4GHz Infrastructure:

Unrivaled 50W Output Power: Delivers a blistering 47dBm (50W) across the entire 3000-4000MHz range—the highest power available in this compact form factor. Ensure link closure in high-density urban deployments, long-range backhauls, and contested electromagnetic environments.
Next-Generation GaN-on-SiC Technology: Harnesses the latest Gallium Nitride-on-Silicon Carbide (GaN-on-SiC) HEMT technology to achieve ≥45% power-added efficiency, setting new benchmarks for power density, thermal performance, and long-term reliability in 24/7 infrastructure applications.
Precision-Tuned for C-Band Spectrum: Optimized 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 (3.4-4.2GHz), and various radar and telemetry frequencies.
Ultra-Linear 40dB Gain: A high-dynamic-range 40dB gain stage preserves the most complex waveforms (256/1024-QAM, OFDMA, FMCW chirps) with industry-leading EVM performance, ensuring spectral efficiency and data integrity at peak power.
Military-Grade IP54 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 extreme shock, vibration, thermal cycling, and environmental exposure.
Universal Integration Architecture: Features SMA-K (female) RF connectors, heavy-duty AWG18 power leads, and a 3-28V TTL-level control line for seamless integration with network management systems, remote site controllers, and tactical command interfaces.
Extended Environmental Certification: Qualified for continuous operation from -30℃ to +85℃, ensuring peak performance in outdoor enclosures, unventilated shelters, and extreme climates—from arctic to desert deployments.

Required Cooling Solution (For Continuous 50W Operation):

To harness 50W continuously in infrastructure applications, industrial-grade thermal management is absolutely mandatory:

Heatsink Base: ≥ 20 mm thick oxygen-free copper or high-efficiency aluminum
Fin Array: ≥ 50 mm tall, high-density fin array optimized for forced or natural convection
Airflow: 50+ CFM high-static-pressure fan for enclosed installations; for tower mounts with natural convection, significantly larger fin surface required
Thermal Interface: Premium thermal paste or phase-change material with <0.05°C/W thermal resistance
Monitoring: Recommended temperature sensor integration for active thermal management and remote monitoring

Critical Operational Notes:

Power Supply Requirement: Requires a heavy-duty, low-ripple 28V / 6A minimum DC power supply. For 24/7 infrastructure deployment, a 28V / 8A redundant power supply with backup is strongly recommended.
Thermal Management is ABSOLUTELY CRITICAL: At 50W output, the power density is extreme. The amplifier must be mounted to a high-performance heatsink with appropriate airflow for any duty cycle above 20%. Operation without proper cooling will result in immediate thermal shutdown or catastrophic failure.
Strict Power-Up Sequence: To prevent oscillation and damage, follow this sequence without exception: (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 (47dBm), drive the amplifier with 7-8dBm input. The gain is 40dB, so 7dBm input yields 47dBm output. Do not exceed +10dBm input under any circumstances.
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 management systems.

Flagship Applications (3-4GHz):

5G NR Macro Cell Networks: Power 3.3-3.8GHz base stations for nationwide coverage, high-capacity urban cores, and rural broadband initiatives.
Defense & Air Defense Radars: Drive long-range surveillance radars, weather radar systems, and air defense acquisition radars with 50W of clean power.
