Device Overview

General Description

The MMD-1030LCSM is a MMIC doubler fabricated with GaAs Schottky diodes. This part operates over a 5 to 15 GHz input frequency range or a doubled output frequency range of 10 to 30 GHz. It features excellent conversion loss, superior isolations, and harmonic suppressions across a broad bandwidth. It is available as a 3x3mm QFN and connectorized evaluation board.
