Microwave Power Modules
for Defense Applications

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.
