Frequency Doublers

ACST offers a set of frequency doublers and triplers for high power and wide band applications based on our high power Schottky varactor-diodes technology.

Frequency doublers are an efficient option to increase the frequency of a source beyond W-band while maintaining the power level required for a wide range of applications.

High Efficiency Doublers

ACST’s high power doublers are able to handle the power provided by most of the E-band and W-band amplifiers available in the market. Frequency doublers is our most efficiently option to provide high power sources width up to 40% efficiency and 180 mW at 170 GHz, and 30% efficiency and 40 mW at 340 GHz without power combining techniques. Power combining technique can increase the offered power in a factor two to four.
