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.<>
