Abstract: Systems, methods, and circuitries are provided for a local oscillator (LO) signal distribution. An exemplary LO distribution network includes a common LO buffer configured to buffer an LO signal, a receive (RX) LO buffer, and a transmit (TX) mixer in a cascaded arrangement. The RX LO buffer is configured to receive the LO signal and buffer the LO signal and to provide the LO signal to an RX mixer. A first LO signal line and a second LO signal line are configured to conduct the LO signal from the common LO buffer to the RX LO buffer. The RX LO buffer is coupled to the first LO signal line and the second LO signal line. The TX mixer is also coupled to the first LO signal line and the second LO signal line.

Abstract: An integrated circuit device includes a variable gain amplifier with multiple gain circuits coupled in parallel, where one or more of the multiple gain circuits comprises a first differential pair of transistors, and a complementarily switched second differential pair of transistors cross-connected to the first differential pair of transistors with a sign inversion relative to the first differential pair of transistors. Other examples are disclosed and claimed.

Abstract: A transmit receive switch (TRSW) system is disclosed. The system has a transmission line, a transformer based matching network, a shunt switch, an amplifier and circuitry. The transmission line is connected to an antenna port. The transformer based matching network is connected to the transmission line and has a first coil and a second coil, wherein the second coil is connected to the transmission line. The amplifier can be configured as a shunt switch when inactive. The shunt switch, including the amplifier configured as the shunt switch, can be connected to the first coil of the transformer based matching network. The circuitry is configured to cause the shunt switch to be ON during an inactive mode and create a short across the first coil. Combined, the length of transmission line needed to complete the impedance transformation is reduced, thereby lowering the overall insertion loss of the transmit/receive switch.

Abstract: Example antenna module includes antenna units provided over an antenna unit support, and ICs communicatively coupled to various antenna units. The ICs are arranged in two or more subsets of one or more ICs in each subset, where an individual IC belongs to only one subset, different subsets are in different layers with respect to the antenna unit support, and an average pitch of projections of all of the ICs onto a plane parallel to the antenna unit support is substantially equal to, or smaller, than an average pitch of the antenna units. When an average width of the ICs is larger than the average pitch of the antenna units, arranging the ICs in two or more subsets in different layers means that at least one of the ICs of one subset partially overlaps with at least one of the ICs of another subset.

Abstract: Various aspects provide a transceiver and a communication device including the transceiver. In an example, the transceiver includes an amplifier circuit including an amplifier stage with an adjustable degeneration component, the amplifier stage configured to amplify a received input signal with an adjustable gain, an adjustable feedback component coupled to the amplifier stage; and a controller coupled to the amplifier stage and to the adjustable feedback component and configured to adjust the adjustable feedback component based on an adjustment of the adjustable degeneration component.

Abstract: Disclosed herein are electronic assemblies, integrated circuit (IC) packages, and communication devices implementing three-dimensional power combiners. An electronic assembly may include a first die, comprising a first transmission line, and a second die, comprising a second transmission line. Each die includes a first face and an opposing second face, and the second die is stacked above the first die so that the first face of the second die is coupled to the second face of the first die. The electronic assembly further includes a first conductive pathway between one end of the first transmission line and a first connection point at the first face of the first die, a second conductive pathway between one end of the second transmission line and a second connection point at the first face of the first die, and a third conductive pathway between the other ends of the first and second transmission lines.
