A fully-electronic high-speed transmission with a highly-integrated set of quadrature direct-conversion TX and RX modules in 130nm SiGe HBT technology operating in the 240 GHz transmission window is presented. In view of high packaging costs of the currently available THz communication front-ends, each of the modules is implemented as a single chip with a broadband silicon lens-integrated on-chip...
This paper presents a fully integrated direct-conversion quadrature transmitter and receiver chipset at 240 GHz in a 0.13 μm SiGe HBT technology with fT/fmax of 350/550 GHz. This chipset is suited for applications requiring both fixed and tunable LO which is made possible due to a wideband frequency multiplier (×16) based local-oscillator (LO) signal source and a wideband on-chip antenna designed...
