Solid-State Power Amplifiers

Spatium™ Technology

TriQuint's patented Spatium™ RF power combining technology provides a highly reliable, efficient alternative to traveling wave tube amplifiers (TWTAs) for commercial and defense communications, radar, electronic warfare (EW) and other defense systems.

Spatium solutions are readily customizable and dramatically improve broadband RF power and efficiency through patented coaxial spatial combining techniques using gallium arsenide (GaAs) or gallium nitride (GaN) MMIC amplifiers. Spatium's all solid-state construction delivers longer service lifetimes than comparable TWTAs or conventional planar power combining products; they provide clear size, weight and power (SWaP) advantages. RF designers can use Spatium to achieve unprecedented efficiency with output power from hundreds to thousands of watts.

Key Benefits

  • Ultra-broadband operation: Up to decade BW
  • Efficiently combines 8, 10, 16 or up to 32 amplifiers
  • 93% combining efficiency / High PAE
  • Smaller than comparable TWTAs
  • High reliability: 7+ years compared to TWTAs
  • Graceful degradation

Applications

  • Electronic warfare
  • Radar systems
  • Communications
  • Test and measurement
