Modern L-, S-, C-band transceivers are built based on quadrature signal processing, implemented on the basis of quadrature signal generator (QSG) integrated circuits. The paper provides an overview of the types, calculation methods and characteristics of integrated QSG that are widely used in the construction of complex-functional blocks of the transceiver devices. The opportunity to improve the performance of the QSG, developed on the basis of SiGe BiCMOS technology, is shown. The results of design and simulation characteristics of schematic diagrams, layout QSG based on LC-, RC-networks, triggers for frequency range 1–4GHz is shown.
