Device Overview

General Description

The MMD-2050HSM is a passive MMIC millimeter wave doubler fabricated with GaAs Schottky diodes. This operates over a guaranteed 10 to 25 GHz input frequency range or a doubled output frequency range of 20 to 50 GHz. It features excellent conversion loss, superior isolations, and high harmonic suppressions across a broad bandwidth. Both surface mount QFN and evaluation boards are available.

[1][2][3] Isolation is defined as the harmonic power relative to the 1F fundamental input power.

[4][5][6] Suppressions and isolations measured with an input source with >60dBc (relative to fundamental input) harmonic suppression. Suppression is defined as the harmonic power relative to the 2F doubled output power.
