Abstract: A blocker signal removal device suitable for a receiver input unit, and a method of using the same are proposed. The blocker signal removal device effectively removes blocker signals in reception signals for the receiver. The blocker signal removal device includes a balun low-noise amplifier having a single input and differential output and a filter circuit coupled to the balun low-noise amplifier and configured to remove only an in-band signal of the reception signals. According to such a configuration, signals of the balun low-noise amplifier and signals of the filter circuit cancel out each other, so that unwanted out-of-band signals are removed from the reception signals, and only the in-band signal remains.

Abstract: Disclosed is an RF switch device and, more particularly, an RF switch device having an air gap over a gate electrode and a metal interconnect at a position higher than the air gap and that at least partially overlap the air gap in the vertical direction, thereby preventing exposure of an upper portion of the air gap in subsequent processing.

The RF switch device includes a first active region on a first substrate as a first base, a second active region on the first substrate spaced apart from the first active region as a second base, and a gate electrode on the first active region and on the second active region.

The semiconductor device includes impurity regions formed in surface portions of a substrate, gate structures formed on surface portions of the substrate between the impurity regions, a first insulating layer formed on the impurity regions and the gate structures, first wiring patterns formed on the first insulating layer, and first contact patterns connecting the impurity regions and the first wiring patterns through the first insulating layer, and the first wiring patterns are arranged in a zigzag shape.

Abstract: An RF switch device and a method of manufacturing the same are disclosed. More particularly, an RF switch device in a stacked configuration and a method of manufacturing the same seeking to reduce or eliminate a voltage imbalance, a condition in which different voltages are applied to different stages of the RF switch device, by forming air gaps on or over corresponding gate electrodes, in which each of the air gaps in a single stage has a different width.
