Abstract
A single-chip millimeter-wave transmitter module in which GaAs IMPATT diodes are monolithically integrated with a microstrip resonator and a loop antenna is discussed. Devices operating at 43.3 GHz produce 27-mW CW output power with 7.2% conversion efficiency. Radiation patterns of linear arrays of such radiating elements were determined as a function of interelement spacing and number of elements. The oscillator chip was also directly coupled to and power combined in waveguides, producing an inexpensive millimeter-wave source.Keywords
