    Abstract: An impedance matching circuit is provided. The present impedance matching circuit is able to match impedance using a transformer which is arranged inside a dielectric substrate and arranged to overlap with a bonding pad area and an end of a transmission line, thereby enabling transmitting signals at a desired frequency with a minimum insertion loss without using a very thin transmission line which is several to dozens of μm wide or specially designed antennas in order to compensate for inductance. Thus, the present impedance matching circuit may be applied to various millimeter bands.

    Abstract: A radio frequency (RF) switch with a transformer and a switching method thereof are provided. The RF switch includes a transmitting end transformer having a primary side connected to a transmitting end and a secondary side connected to an antenna; and a receiving end transformer having a primary side connected to the antenna and a secondary side connected to a receiving end. In a transmission mode, the transmitting end transformer is tuned on, and, in a reception mode, the receiving end transformer is turned on. Accordingly, since switching is performed based on transformers rather than transistors connected in series, the RS switch, which can achieve high linearity and low insertion loss as well as high isolation, can be implemented.
