Prometheus
-
The design of the Prometheus is the result of over 10,000 hours of research and development, encompassing hundreds of hours of mathematical analysis, computer simulation and modeling, and numerous prototypes and experiments spanning over a five year period. The result is a rugged, commercial quality amplifier designed to run cool under 1500W continuous SSB, CW or RTTY, with special ferrite transformers and combiners designed for full power operation even on 160 meters. Although our custom transformers are more expensive and difficult to manufacture than competing designs, they do not saturate or heat up beyond the Curie point, thereby becoming irreversibly damaged and destroying the RF transistors in the process.

Difference Amplifiers
-
A difference amplifier is a special purpose amplifier designed to measure differential signals, otherwise known as a subtractor. A key feature of a difference amplifier is its ability to remove unwanted common mode signals, known as common mode rejection (CMR). Unlike most types of amplifiers, difference amplifiers are typically able to measure voltages beyond the supply rails, and are used in applications where large dc or ac common-mode voltages are present. They are ideal for current and voltage monitoring. Analog Devices offers a range of difference amplifiers, optimized for low distortion, low power, or high voltage performance.
