About Us

Q. Can you give us a brief history of AMCOM Communications? When was the company founded and what was the objective?

AMCOM was established in December 1996 by Dr Ho Huang and Dr Amin Ezzeddine, experienced RF engineers who met at Comsat (Communications Satellite Corporation)and eventually ventured out to build their own company. Experienced in both microwave circuit design and microwave device fabrication, it did not take long for AMCOM to become a valuable addition to the RF microwave sector. The Company is in Gaithersburg, Maryland, USA, about 20 miles northwest of Washington, DC. The objective has always to become the most sought-after RF microwave design and manufacturing company in the industry. 

AMCOM is fabless which refers to a company that develops and holds intellectual property (IP) while outsourcing the fabrication of its semiconductors. We outsource manufacturing of our semiconductors to leading foundries in the USA, Europe and Asia.

Regardless of the market segment that we are targeting, our power amplifiers are characterized by the following parameters:

  • Frequency range: The range of frequencies over which the amplifier can operate.
  • Gain: The amount by which the amplifier increases the power of the signal.
  • Output power: The maximum power that the amplifier can output.
  • Efficiency: The ratio of the output power to the input power.
  • Noise figure: The amount of noise added by the amplifier to the signal.

We design and manufacturer our power amplifiers for a variety of applications and market segments as discussed previously, each with its own specific requirements. For example, an amplifier used in a cellular base station will need to have a high gain and output power to cover a large area, while an amplifier used in a medical diathermy device will need to be highly efficient and have low noise. Here are some of the key factors that are considered when we set out to design our amplifiers:

  • The target application: The specific requirements of the application will determine the design of the amplifier.
  • The frequency range: The frequency range of the amplifier will determine the type of transistors and other components that can be used.
  • The power requirements: The power requirements of the application will determine the size and complexity of the amplifier.
  • The efficiency requirements: The efficiency requirements of the application will determine the type of amplifier topology that is used.
  • The cost: The cost of the amplifier will need to be balanced against the performance requirements.

Our power amplifiers are a complex and challenging to design, but they are essential components in a wide range of important applications.

Q. Which semiconductor technologies do you use for developing your products? What is the breakup between GaAs and GaN Technologies. How has this changed over the last few years?

We use gallium arsenide (GaAs) and gallium nitride (GaN) substrates. As you know, they're both widely used in our field for microwave and RF applications, but each has its own unique characteristics and shines in different situations.

Crystal Structure and Lattice Matching:

  • GaAs: ThisⅢ-Ⅴsemiconductor boasts a zincblende crystal structure, making it a perfect match for silicon (Si) substrates. This lattice matching enables the growth of high-quality epitaxial layers, crucial for device performance.
  • GaN: Belonging to the sameⅢ-Ⅴfamily, GaN also boasts a zincblende structure.

Material Properties:

  • GaAs: This veteran player scores high on electron mobility, making it excellent for high-frequency applications. It also boasts decent thermal conductivity, but not stellar. On the flip side, its wide bandgap of 1.42 eV limits its power handling capability.
  • GaN: Boasting a whopping 3.4 eV. This translates to superior breakdown voltage and power handling, making it ideal for high-power RF applications. Plus, its thermal conductivity is almost three times that of GaAs, keeping things cool under pressure. However, its electron mobility is lower, putting it at a disadvantage in some high-frequency scenarios.

Cost and Availability:

  • GaAs: Mature technology and widespread adoption make GaAs substrates relatively inexpensive and readily available. This affordability makes it a popular choice for a long time.
  • GaN: While GaN technology is rapidly advancing, it's still relatively young. This translates to higher substrate costs compared to GaAs. However, the price gap is narrowing as GaN production ramps up.


  • GaAs: Due to its excellent high-frequency performance and affordability, GaAs reigns supreme in low-to-medium power applications like:
    • Cellular and Wi-Fi infrastructure
    • Microwave communication systems
    • Satellite communications
    • Radar systems (lower frequencies)

  • GaN: Its high power handling and wide bandgap make GaN the champion for high-power applications like:
    • Radar systems (higher frequencies)
    • Power amplifiers for base stations and mobile devices
    • Microwave heating
    • Solid-state power supplies

Both our GaAs and GaN substrates provide superior performance and durability. The choice between them depends on the specific requirements of our customers application. If they prioritize high frequency and affordability, GaAs is the best fit. But if they need to crank up the power and handle wider bandwidths, GaN is the best choice.
