    Abstract: An apparatus is disclosed for oscillator feedthrough calibration, such as a component arrangement that can be calibrated to account for signal leakage from an oscillator coupled to a mixer circuit. In example aspects, the apparatus includes a mixer circuit having a first stage, a second stage, and tuning circuitry. The first stage includes at least one transistor coupled between a mixer input and a mixer output. The second stage includes one or more transistors coupled between the at least one transistor of the first stage and the mixer output. The one or more transistors are also coupled between a local oscillator signal input and the mixer output. The tuning circuitry includes at least one current source coupled to the at least one transistor of the first stage.

    Abstract: Aspects described herein include devices and methods with chain routing of signals for massive antenna arrays. In some aspects, an apparatus is provided that includes a first millimeter wave (mmW) transceiver having a first port, a second port, one or more antenna elements, a plurality of chain mmW transceiver ports, and switching circuitry. The switching circuitry is controllable by control data to route portions of a merged clock and data signal and a merged control and data signal between a first route between the one or more antenna elements and the first port and a second route between the one or more antenna elements and the second port and a third route between the first port and the plurality of chain mmW transceiver ports and a fourth route between the second port and the plurality of chain mmW transceiver ports.
