A 135GHz SiGe transmitter with a dielectric rod antenna-in-package for high EIRP/channel arrays

In this paper, a 135 GHz antenna-in-package (AiP) transmitter with high equivalent isotropic radiated power (EIRP) is presented. The radiating element is realized by a dielectric rod antenna fed by a planar Yagi-like electric dipole. A SiGe transmitter composed of an active balun, 8× frequency multiplier and a power amplifier is mounted on the AiP. The operating frequency of the system is 125-140 GHz. The measured EIRP at 135 GHz is 15.6 dBm and the DC power consumption is 366 mW.
