Linearized 4-7 GHz LC Tunable Filter with Active Balun in 0.18um SiGe BiCMOS
… the microwave regime. A balanced-to-unbalanced (balun) transformation circuit is required to support the differential nature of a tunable LC filter. An active balun that also performs as a transconductor to drive the LC tank would relax the design requirement for the LNA and remove a passive …

Radio frequency direct-digital QPSK modulators in CMOS technology
… (RC-CR) phase shifter followed by two 180° active baluns. One signal from the in-phase components and another from the quadrature-phase components are later selected by two PTL circuits according to the in-phase (I) and quadrature-phase (Q) digital data respectively. Finally the chosen …
