ACASOM 10W 6-7.2GHz GaN Amplifier PCBA: 40dBm of Power in an 8.7g Package for the 6GHz Frontier

Introduction: The 6GHz Frontier Demands a New Class of Power

The wireless landscape is shifting. As 5.8GHz grows increasingly congested with FPV feeds, WiFi networks, and countless consumer devices, a new spectrum frontier is opening: 6GHz. This band—spanning 6 to 7.2GHz—offers wider channels, cleaner airwaves, and unprecedented bandwidth for applications ranging from next-generation FPV video to WiFi 6E/7 telemetry and advanced drone communication links.

But higher frequencies come with a physical reality: path loss. Signals at 6GHz attenuate faster over distance than their 5.8GHz counterparts. To truly exploit this new spectrum, you need power—and you need it without the weight penalty that traditionally accompanies high-power RF amplification.

Enter the ACASOM 10W 6-7.2GHz Broadband FPV VTX Amplifier PCBA. This bare-board module represents a breakthrough in power-to-weight engineering. Leveraging advanced Gallium Nitride (GaN) technology, it delivers a formidable 40dBm (10W) output in a package that weighs just 8.7 grams. For FPV pioneers, drone integrators, and RF developers pushing into the 6GHz frontier, this amplifier transforms what’s possible.

Product Overview: Purpose-Built for the 6GHz Revolution

The ACASOM amplifier is not a repurposed 5.8GHz design. It is purpose-engineered for the 6000-7200MHz range, covering emerging 6GHz FPV bands, the full WiFi 6E unlicensed spectrum (5.925-7.125GHz), and next-generation 7GHz communication systems.

Its bare-board PCBA form factor—measuring just 69x38x4mm—is designed for integration into weight-critical builds. Unlike bulky enclosed amplifiers that add hundreds of grams to a drone or ground station, this module slips into tight frames, disappears into custom enclosures, and allows developers to embed 10W of clean RF power exactly where it’s needed.

Who needs this amplifier?

• FPV pioneers: Early adopters exploring 6GHz video transmission for interference-free, extreme-range flights.

• Drone integrators: Commercial UAV builders deploying WiFi 6E telemetry links for high-bandwidth data streaming.

• RF developers: Engineers prototyping 6-7GHz communication systems, radar modules, or custom wireless hardware.

• Extreme-range enthusiasts: Pilots pushing the limits of 5.8GHz with an eye toward a future-proof 6GHz upgrade path.

Core Technologies: The GaN Advantage

Gallium Nitride: Efficiency That Transforms Performance

At the heart of this amplifier lies Gallium Nitride (GaN) technology. Unlike traditional silicon or even Gallium Arsenide (GaAs), GaN enables higher power density, greater efficiency, and smaller form factors. The result is a ≥45% power-added efficiency at full 10W output.

What does this mean for your build?

• Less heat: More input power converts to RF output rather than waste heat, easing thermal management demands.

• Lower current draw: Reduced strain on your flight battery, preserving flight time and system stability.

• Cleaner signal: High-efficiency GaN devices contribute to better linearity, preserving video quality even at extreme output levels.

10W (40dBm) Output: The Range Multiplier

With 40dBm of saturated output power, this amplifier provides a massive link budget advantage over standard 1W (30dBm) or 200mW (23dBm) VTX units. In practical terms, this can translate to double or triple the effective range under line-of-sight conditions, or the ability to maintain a stable video feed through light obstacles that would cripple lower-power systems.

For context: a 10W signal has 10 times the power of a 1W signal—a 10dB advantage in link budget terms. When paired with a high-gain antenna, the range potential becomes extraordinary.

38dB Gain: Amplify From Almost Any Source

The amplifier provides 38dB ±1 of gain, allowing it to take a very modest input signal and boost it to full power. The recommended input range is -13dBm to +10dBm, with optimal performance achieved at 3-4dBm input—easily delivered by most modern FPV VTX units or signal generators.

A key feature is the integrated control line (3-28V) , enabling remote on/off switching. This allows integration with a flight controller’s auxiliary output, letting you power down the amplifier during close-range flight to conserve battery, then activate it for long-range pushes.

Core Applications: Where 10W at 6GHz Matters

6GHz FPV Pioneering

For pilots ready to explore the newly available 6GHz spectrum, this amplifier is the essential enabler. When paired with a 6GHz-capable VTX and a high-gain 6GHz antenna, it delivers clean, powerful video transmission in a band that remains largely free of interference. The result is extreme-range FPV with video clarity that rivals wired connections.

WiFi 6E/7 Drone Telemetry

Commercial UAV operations increasingly demand high-bandwidth telemetry for real-time data streaming, payload control, and beyond-visual-line-of-sight (BVLOS) missions. By boosting a WiFi 6E module’s output, this amplifier enables long-range, high-throughput telemetry in the uncongested 6GHz spectrum—ideal for industrial inspections, mapping, and search-and-rescue applications.

Extreme Long-Range 5.8GHz FPV (Future-Ready)

While optimized for 6-7.2GHz, this amplifier can serve as a future-proof investment for pilots currently flying on 5.8GHz. As 6GHz equipment becomes more widely available, the same amplifier can transition seamlessly to the new band, protecting your investment while delivering 10W performance today.

Research & Development

For labs and engineering teams prototyping 6-7GHz communication systems, radar modules, or custom RF hardware, this compact PCBA provides a professional-grade power stage in a developer-friendly format. Its bare-board design allows for direct integration into test setups and proof-of-concept builds.

Integration Guide: Getting the Most From Your Amplifier

Power Supply Requirements

The amplifier requires a stable 24-28V DC supply. For full 10W output, a 28V / 1.5A power source is recommended to provide adequate headroom. Ensure the supply is clean and well-regulated to avoid injecting noise into the RF chain.

Thermal Management is Essential

With 10W output and 45% efficiency, approximately 12W of heat must be dissipated. In weight-critical builds, passive cooling may suffice with adequate airflow. For continuous operation or enclosed installations, active cooling—such as a small fan and properly sized heatsink—is strongly recommended. The 8.7g form factor prioritizes weight, but thermal consideration is non-negotiable for reliability.

Critical Connection Sequence

To prevent damage from reflected RF power, follow this sequence without exception:

1. Connect the antenna to the amplifier’s output.

2. Apply DC power to the amplifier.

3. Enable your RF source (VTX or signal generator).

Operating the amplifier without an antenna load can cause immediate and permanent damage.

Control Line Integration

The control line accepts 3-28V for remote on/off switching. Connect it to a flight controller’s auxiliary output, a dedicated switch, or a power management system to enable the amplifier only when needed.

PCBA Handling Precautions

As a bare-board module, proper handling is critical:

• Insulate the board to prevent shorts against carbon fiber frames or conductive surfaces.

• Secure the module firmly using non-conductive mounting hardware to protect against vibration.

• Use quality RF cables rated for 6-7.2GHz to preserve output power.
