Abstract: A semiconductor package includes a leadframe having a die pad and lead terminals along a perimeter of the die pad, and an IC die mounted on the die pad. The IC die includes I/O pads disposed on an active front surface of the IC die. The IC die includes a semiconductor substrate, a circuit block fabricated on the semiconductor substrate, and a through substrate via (TSV) extending through a thickness of the semiconductor substrate. Bond wires extend between the I/O pads and the lead terminals, respectively. A molding compound encapsulates the IC die, the bond wires, and the leadframe.

Abstract: A radio frequency (RF) front-end circuit of a wireless communication device is provided. The RF front-end circuit includes a receiving amplifier, a down-converter, an up-converter, a transmitting amplifier and an output driver, where the receiving amplifier and the down-converter are configured to process received signals according to a local oscillation (LO) signal, and the up-converter, the transmitting amplifier and the output driver are configured to process transmitted signals according to the LO signal. The receiving amplifier, the up-converter or the transmitting amplifier includes a transformer load. The transformer load includes a switchable inductor. When the wireless communication device operates in a first mode, the LO signal has a first frequency, and the switchable inductor has a first inductance. When the wireless communication device operates in a second mode, the LO signal has a second frequency, and the switchable inductor has a second inductance.
