Device Overview

General Description

The D-0308 is a passive doubler fabricated with silicon Schottky diodes. This operates over a guaranteed 3 to 8 GHz input frequency range or a doubled output frequency range of 6 to 16 GHz. It features excellent conversion loss, isolations, and harmonic suppressions across a broad bandwidth. D series doublers have generally been replaced with MMD doublers with superior performance, repeatability and availability. The D-0308 is still used in legacy systems and is suitable for laboratory use.
