Abstract
A hybrid balun apparatus are disclosed. The hybrid balun apparatus can support both the reception mode and the transmission mode and be advantageous for a high level of integration, by replacing two transformers disposed at a reception path and a transmission path with a single transformer and integrating a T/R switch and a balun into a one chip. Therefore, an IC according to integration extends to a front stage of an antenna to facilitate interfacing between elements, and a burden for designing at a rear stage (i.e., LNA in the reception mode, and PA in the transmission mode) can be reduced.
