A semiconductor package includes a ground electrode formed on an upper surface of a substrate, a first electronic component disposed on the upper surface of the substrate, a sealing member sealing the electronic component, and a shielding member surrounding the first electronic component and disposed in the sealing member.

Semiconductor package and manufacturing method thereof

A radio frequency switch apparatus includes switching circuits connected between respective signal terminals and an antenna terminal. Each of the switching circuits includes a series switching circuit and a shunt switching circuit configured to switch a signal band on and off. An inductor circuit includes an inductor device connected between at least one shunt switching circuit of the switching circuits and a ground. The inductor device suppresses noise and passes the signal band by being resonant with a capacitance present upon the shunt switching circuit being turned off.

Radio frequency switch apparatus having improved noise suppression characteristics

A hybrid inductor includes a board, a first inductor provided in the board and including conductive patterns disposed at different heights, and a second inductor mounted on the board and an end of the second inductor being connected to the conductive patterns. Since mutual inductance is generated, inductance higher than a capacity value of a single inductor may be obtained.

Hybrid inductor
