AMKOM AKG-6W Ku-Band BUC | Introduction

by Hamid Bagheri  |  August 1, 2026

As satellite communication networks continue to evolve, the demand for compact, energy-efficient, and highly reliable RF equipment has never been greater. Modern VSAT terminals, enterprise satellite networks, government communication systems, maritime platforms, and mobile SATCOM deployments require hardware that delivers consistent RF performance while minimizing power consumption and installation complexity.

The AMKOM AKG-6W Ku-Band Block Upconverter (BUC) has been developed specifically to meet these requirements. Designed by Amkom Design Group, the AKG-6W combines a lightweight mechanical design, low power consumption, excellent RF characteristics, and military-grade reliability into one of the industry’s most compact 6W Ku-Band BUC solutions.

At VSATplus, we proudly offer the AMKOM AKG-6W Ku-Band BUC to customers worldwide, providing genuine products, competitive pricing, expert technical consultation, and global shipping for professional satellite communication projects.


The AKG-6W belongs to AMKOM’s latest generation of Fanless Slim Ku-Band Block Upconverters, specifically engineered for professional outdoor satellite terminals.

A Block Upconverter (BUC) converts the Intermediate Frequency (IF) signal generated by a satellite modem into the Ku-Band uplink frequency before transmitting it toward the satellite. The AKG-6W performs this conversion while delivering 6 Watts of saturated RF output power (37.8 dBm) with remarkably low power consumption.

Unlike conventional BUCs that require bulky housings and active cooling, the AKG-6W features a fanless ultra-compact enclosure weighing less than one pound, making it ideal for portable, mobile, and space-constrained satellite terminals. 


Designed for Modern Satellite Networks

Satellite communication operators increasingly require equipment that is:

  • Lightweight
  • Energy efficient
  • Reliable in harsh environments
  • Easy to integrate
  • Low maintenance

The AKG-6W was designed around these principles.

According to the product documentation, this model represents AMKOM’s next-generation Fanless Slim Non-IP Series, utilizing highly efficient RF amplifiers with internal overdrive protection while maintaining excellent RF stability and low phase noise. Every unit undergoes comprehensive acceptance testing at the company’s California manufacturing facility before shipment. 


The AKG-6W offers an impressive feature set for a compact 6W outdoor BUC.

Highlights include:

  • 6W Ku-Band RF Output
  • Ultra-Lightweight Design (Less than 1 lb / 0.45 kg)
  • Fanless Cooling
  • Extremely Low Power Consumption
  • Internal Overdrive Protection
  • High RF Stability
  • Excellent Phase Noise Performance
  • Weather-Resistant Outdoor Construction
  • Optional Advanced Monitor & Control
  • 3-Year Manufacturer Warranty

These features make the AKG-6W suitable for both fixed and transportable VSAT terminals. 


One of the most attractive characteristics of the AKG-6W is its size.

The enclosure measures only:

  • 139 × 64 × 40 mm
  • 5.46 × 2.52 × 1.575 inches

while weighing:

  • Less than 0.45 kg (1 lb)

Despite its small footprint, the unit delivers professional RF performance typically associated with much larger outdoor amplifiers. 


Reliable RF performance is essential for maintaining stable satellite links.

The AKG-6W provides:

  • 6W Saturated Output Power (37.8 dBm)
  • 5W Linear Output Power (37.0 dBm)
  • Excellent gain stability
  • Very low spectral regrowth
  • Low AM/PM conversion
  • Low group delay ripple
  • Excellent spurious suppression

These specifications enable operators to maximize satellite link performance while maintaining signal integrity. 


The AKG-6W supports multiple Ku-Band configurations to accommodate different satellite operators and regional frequency plans.

Available models include:

Standard Ku-Band

  • RF: 14.0 – 14.5 GHz

Universal Ku-Band

  • RF: 13.75 – 14.5 GHz

Dual Ku-Band

  • RF:
    • 13.75 – 14.5 GHz
    • 14.0 – 14.5 GHz

Corresponding IF frequencies include:

  • 950–1700 MHz
  • 950–1450 MHz

with Local Oscillator options of:

  • 12.80 GHz
  • 13.05 GHz

This flexibility allows the AKG-6W to integrate with a wide variety of VSAT platforms. 


Power efficiency is increasingly important for remote sites powered by batteries, solar systems, or limited electrical infrastructure.

The AKG-6W consumes only:

  • 23 Watts at full 6W RF output
  • Approximately 12 Watts during lower power operation

This makes it one of the industry’s most efficient BUCs in its power class, reducing operating costs and heat generation. 


Unlike many outdoor BUCs, the AKG-6W eliminates mechanical cooling fans.

Advantages include:

  • Silent operation
  • Improved reliability
  • Lower maintenance
  • Reduced dust ingress
  • Longer operational lifespan
  • Better resistance to harsh environments

The passive cooling design also contributes to the unit’s compact dimensions and lightweight construction. 


The AKG-6W has been engineered for high-quality satellite transmissions.

Performance specifications include:

  • IMD3: −25 dBc
  • Spectral Regrowth: −30 dBc
  • In-band/Out-band Spurious: −60 dBc max
  • Group Delay Ripple: 1 ns max
  • AM/PM Conversion: 1.0°/dB max
  • Noise Power Density (TX): −85 dBm/Hz
  • Noise Power Density (RX): −155 dBm/Hz

These characteristics ensure clean uplink signals that comply with satellite operator requirements. 


Phase noise directly affects modulation quality, especially for higher-order modulation schemes.

The AKG-6W exceeds IESS-308 and IESS-309 phase noise standards and offers:

OffsetPhase Noise
10 Hz-55 dBc/Hz
100 Hz-65 dBc/Hz
1 kHz-75 dBc/Hz
10 kHz-85 dBc/Hz
100 kHz-95 dBc/Hz

These values contribute to stable carrier performance and improved satellite link reliability. 


The AKG-6W incorporates several protection mechanisms to maximize operational reliability.

Built-in protections include:

  • Voltage Protection
  • Over-Temperature Protection
  • Current Protection
  • Internal Overdrive Protection
  • Smart Monitoring & Alarms
  • Microphonic Protection

These features help protect both the BUC and connected equipment from abnormal operating conditions.
