This work describes an UWB impulse transmitter with integrated antenna in the 60 GHz band implemented in CMOS65nm SOI technology. The transmitter aims low-power short-range high data-rate communication systems for fast-downloading applications. It consists of an oscillator that is switched on-and-off by the digital data to be transmitted and a medium power amplifier. The transmitter is fabricated on two chips: one for direct on-chip measurements and another one implementing an integrated antenna. The transmitter measurements are performed on-chip and in free space in both continuous wave and impulse operating modes. The circuit achieves an equivalent isotropic radiated power of 2 dBm at 56 GHz and a maximum measured data rate of 2.222 Gbit/sec. The overall power consumption is 28 mW under 1.2 V voltage supply.
