Abstract
The design and performance of spatial power combining arrays of FET oscillators are described. The individual oscillators consist of single microstrip patches driven by two FETs oscillating in the push-pull mode. Arrays formed from these elements show nearly perfect power combination in prototype modules operating at 6 GHz. Maximum effective radiated power (ERP) for a four-patch array combining the power of eight FETs is 32.8 dBm. Results for an oscillator using four FETs combining in a single patch are also discussed.<>
