50 Watt Ka Feedmount BUC User Manual

The PowerStream Grid Amplifier is powered by Wavestream’s Grid Amplifier chip
which consists of an array of several hundred transistors which together form an in-
waveguide amplifier as shown in the diagram below:

PowerStream™ Grid Amplifier™ using Patented Spatial Power Combining

Wavestream’s Grid Amplifier architecture provides significant advantages over
traditional SSPAs which use microstrip or waveguide combining. All the MMIC
amplifier outputs are combined in a single stage of combining in air, making the
amplifier highly efficient. Furthermore the signal never traverses a bond wire,
removing a key single point of failure found in traditional amplifiers.
