Application Note: Scalable Power

AR Worldwide has continued to develop and improve our product offerings to meet the needs of the market. This can be seen with our extensive list of product offerings. A major concern in the market is flexibility. Flexibility of the test equipment in the lab is always a concern.

Today many test labs are seeing a continued increase in RF test levels and increased test distances. Automotive, Military, and Aerospace have all seen an increase in RF test levels over the years. This usually would require bigger, more powerful amplifiers replacing the smaller now obsolete amplifiers. AR Worldwide has seen the need for upgradeability to add power instead of replacing power. In addition this high field strength will only be required for a small part of a test labs total testing, leaving this large amplifier under utilized for most of the time. The ability to separate out or split the amplifier for multiple uses would also be extremely beneficial to a test lab. AR Worldwide has responded to this need with a new offering of Scalable Power. As the world moves further and further into the digital and wireless age the need for flexibility of test equipment becomes a necessity.

In order for these amplifiers to be controlled and to work in unison some considerations must be met. The amplifiers need to be combined and controlled by a central location, so the input and output come from one location called the controller. The RF input is pre-amplified and divided through the controller then phase matched cables run to each sub amplifier input. From the sub amplifier output phase matched cables return to the controller to be combined. If these RF cables and sub amplifiers are not phase matched power looses will occur and the system will loose efficiency.
