Abstract:
A 315-GHz source with integrated antenna is presented. It consists of a harmonic oscillator and a patch antenna. The harmonic oscillator is realized based on the push-push topology using a 0.8 µm-emitter transferred-substrate (TS) InP-DHBT technology with an fmax of 320 GHz. The harmonic oscillator together with antenna delivers -10 dBm of output power. DC power consumption is only 21 mW from a 1.6-volt power supply, which corresponds to 0.5 % overall DC-to-RF efficiency. The chip area of the source with integrated antenna circuit is 0.9×0.65 mm2.
