A high performance 650-GHz sideband separating mixer design and results
(IEEE Inst Electrical and Electronic Engineering Inc., 2017)
We presented the design and experimental results of a new sideband-separating (2SB) mixer for 600-720 GHz (ALMA Band 9). Although designed following the classical quadrature hybrid architecture, the emphasis of the ...
Modular 2SB SIS Receiver for 600-720 GHz: Performance and Characterization Methods
(IEEE, 2017)
A modular sideband-separating (2SB) receiver for 600-720 GHz has been built and tested. The used modular design allows to characterize all the parts separately, including testing of the superconductor-insulator-superconductor ...

EVM Analysis for Broadband OFDM Direct-Conversion Transmitters
(Institute of Electrical and Electronics Engineers, 2013-09)
Low-cost OFDM direct-conversion transceivers suffer from signal degradation through the impairments of the analog front-end, e.g., due to in-phase and quadrature (IQ) imbalance, phase noise, and nonlinear power amplifier ...
