Abstract

We have developed and tested a 21 element two-dimensional power-combining array, intended for transmitter applications in future deep space missions. The array uses MMIC phase shifters for beam scanning, MMIC power amplifiers and Vivaldi (Exponentially Tapered Slot Antenna) radiating elements. The measured combining efficiency, referred to the power amplifier output ports, is about 60%.
