Device for generating phase quadrature radiofrequency signals, usable in particular in 5G technology

摘要

Integrated electronic device comprising a mixer module (MXi) comprising a voltage / current transconductor stage (ETT) comprising first transistors (N5, N6) and connected to a mixing stage (ETM) comprising second transistors (N1-N4), in which the mixing stage (ETM) comprises a resistive degeneration circuit (R1-R4) connected to the sources of the second transistors and a calibration input (ECi) connected to the gates of the second transistors and intended to receive a voltage d ' adjustable calibration (VGM), and the sources of the first transistors (N5, N6) are directly connected to a supply cold point (GND).
