When you watch TV or use a cell phone, amplifiers make the signal stronger or the voice clearer. A hybrid, high-powered microwave amplifier from Aria Microwave Systems of Teaneck, NJ enables signals to be stronger while offering potential savings to satellite and cell phone system providers. The amplifier also offers a high-power solid-state solution for high-frequency needs in military, radar, industrial, scientific, and medical applications.

Aria’s microwave amplifier generates high levels of power through a synchronous reaction of large numbers of RF semiconductor transistors within the device.

Using commercially available amplifier components will allow Aria to manufacture ARFCAs inexpensively and price them to compete with vacuum tube technology minus the short lifespan, and while operating without dangerous high voltages. As a result, applications such as UHF phased-array radar and digital TV transmission can become more practical.

How it Works

Aria’s microwave amplifier generates high levels of power through a synchronous reaction of large numbers of RF semiconductor transistors within the device. Because it does not require discrete circuit components, such as capacitors, inductors, and resistors in the RF circuitry, the amplifier also offers greater reliability than not only vacuum-tube-based amplifiers, but commercially available solid-state-based amplifiers, which generally average a six-year lifecycle.

Aria designed the ARFCA to be a simple solution for power amplification — one that flies in the face of the trend to build all modern electronics on printed circuit boards. The design calls for placing a circular disc between cylindrical cavities of an amplifier, onto which are bonded eight or more RF semiconductor transistors. When power reaches the amplifier’s output cavity, the transistors begin to react in sync.

The synchronous reaction subsequently generates a high level of power output that is coupled into the device’s output cavity and then piped out through standard connectors. This increase in amplitude can be used to boost reliability in telecommunications or satellite operations, or increased output for commercial RF heating.
