The spatially power combined amplifier employs a different technique for combining the transistor outputs than traditional MMIC-based amplifiers. Rather than combining in multiple steps, increasing loss and size with each combining stage, all transistor outputs are combined in a single step. Many amplifying elements synchronously amplify the input signal, and their outputs are combined in free space for very high combining efficiency.

Wavestream's two power amplifier technologies, the PowerStream^TM Deck Amplifier and the PowerStream^TM Grid Amplifier, address a wide array of communications, radar, and imaging applications across the microwave and millimeter wave spectrum.
