This paper presents a fully-integrated direct-conversion fundamentally-operated mixer-first quadrature receiver chip working at 240 GHz. It has been implemented in a 0.13-μm SiGe HBT technology with fT/fmax of 350/550 GHz. The chip includes an LO path based on a x16 multiplier with a 3-stage PA, driven externally from the PCB at 14–18 GHz. The LO signal is split in quadrature by a broadband coupler...
This paper reports on the development and experimental characterization of a high data-rate communication link at 240GHz with highly-integrated direct-conversion quadrature transmitter and receiver modules implemented in 130nm SiGe HBT technology with ft/fmax of 350/550 GHz. Both modules employ a low-cost chip-on-board packaging scheme with single-chip TX and RX front-end circuits accommodating wideband...
In this paper, we present an on-off-keying (OOK) modulator with a local oscilator (LO) at 240 GHz for incoherent high data rate communication systems. The modulator topology is similar to a selector where one of the data inputs is connected to the ground and the baseband signal is fed to the clock input. This circuit is implemented in 130 nm SiGe HBT technology with fT/fmax of 250/370 GHz. The measured...
This paper presents a fully integrated direct-conversion quadrature transmitter and receiver chipset at 240 GHz. It is implemented in a 0.13- SiGe bipolar-CMOS technology. A wideband frequency multiplier ( 16) based local-oscillator (LO) signal source and a wideband on-chip antenna designed to be used with an external replaceable silicon lens makes this chipset suited for applications...
