We are a world leader in crossed-field amplifier (CFA) production and development, delivering devices from L- to X-band, with power levels from 60 kW to 5 MW peak.
We offer a comprehensive line of high-performance electronic emitters (e-guns), which can be used in industrial, medical, and research applications.
Our electronic power conditoners (EPCs) transform satellite bus voltages into the high voltages required for speciﬁc Traveling-Wave Tube (TWT) requirements. We have designed, produced, and delivered numerous models with TWTA output power levels ranging from 2 - 330 W and
frequencies from L- to V-Band.
The ONLY Vertically Integrated Space Traveling Wave Tube Amplifier (TWTA ) Supplier in the World!
From station-keeping, orbit-raising, or primary propulsion, our Xenon ION ((XIPS®) Propulsion System includes a space-qualified thruster and power processing units (PPU). Our technical legacy can be found on NASA’s Deep Space 1 and Dawn space crafts.
Stellant’s Inductive Output Tubes (IOT) are designed for high-power, continuous operation at up to 30 kW average output power in 8 VSB or COFDM modulation schemes.
We are a leader in producing high-power state-of-the-art Clustered Cavity™ klystrons for the wide-band Airborne Early Warning and Control System (AWACS).
Stellant’s magnetrons set the standard for performance and cost-effectiveness thanks to their long-lasting high output levels and efficiency.
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.
We are a trusted partner for RF microwave, and millimeter-wave components and subsystems, serving global connectivity and security challenges. We provide a complete catalog of Active and Passive components.
Stellant Systems Engineering Team has successfully adjusted proprietary heritage technology utilized in linearizing TWTAs, extending the capability to SSPAs. This LSSPA (Linearized Solid State Power Ampliﬁer) is a wideband K-Band Power Ampliﬁer.
Stellant thyratrons are robust switching devices suitable for a wide variety of pulse power applications, including radars, particle accelerators, broadcast transmitters.
We have delivered over 20,000 traveling wave tubes (TWTs) for defense purposes as the leading supplier of TWTs for SATCOM radar and instrumentation applications.
Stellant has over 6 decades of experience developing TWTs in support of commercial, civil & military space missions. Our TWTs are key components for space-based communications satellites and range from UHF to V-Band with output power up to 300+ Watts.
We are the ONLY Manufacturer of Space-Qualified TWTs in the USA!
We have six decades delivering TWTAs for space-based applications and recently introduced our Q-Band 200 W Downlink TWTA and V-Band 200 W Uplink TWT to better serve the high-throughput satellite market.
We are the ONLY Vertically Integrated Space TWTA Supplier in the World!
Stellant's K- and Ku-Band Space Quad NanoMPM® is a state-of-the-art RF power ampliﬁer for use in satellite downlink applications. This product
delivers the ultimate performance by leveraging the best of solid-state and TWT vacuum technology.
