Abstract
This paper reports a fully integrated 90 GHz-carrier pulsed transmitter in 0.13 μm SiGe BiCMOS process for imaging applications. To obtain ultra-short programmable pulses, the transmitter employs a number of novel techniques including hybrid switching and Antentronics. The transmit path includes a quadrature VCO, PA driver, PA and the on-chip folded slot antenna. High speed ECL circuits generate and provide the short pulses in several operating modes. The transmitter achieves a record pulsewidth of 26 ps in the hybrid mode and 33 ps in the independent mode. This translates to >30 GHz of RF BW in the transmitter.
