Stellant Systems is the industry leader in Microwave Power Modules (MPMs), having delivered thousands for use in some of the aerospace and defense industry’s most highly-effective platforms. Our MPMs typically include a miniature Helix Traveling-Wave Tube (TWT), a Solid-State Amplifier (SSA) driver and a miniature power supply.

Our MPMs are qualified for space, ground, sea and/or airborne applications and are typically used in Unmanned Aerial

Vehicles (UAVs), Radar and ECM systems, portable and mobile SATCOM systems, and point-to-point communications.

Advancements in MPMs have led to the development of our new NanoMPM®, a compact model qualified for space, airborne, sea or ground applications where size and weight are prime requirements.

Additionally, our IRAD investments are in partnership with government laboratories and federally funded research Institutions in order to advance the state of the art in TWT and MPM technologies.
