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.

Abstract: Certain aspects of the present disclosure are directed to a circuit for signal processing. The circuit generally includes a first transformer having a first inductive element magnetically coupled with a second inductive element, and a second transformer having a third inductive element magnetically coupled with a fourth inductive element, wherein the first inductive element is coupled in series with the third inductive element. In certain aspects, the circuit also includes a first switch coupled in parallel with the third inductive element, a capacitive element coupled in parallel with the fourth inductive element, wherein a notch is formed at least by the capacitive element and the fourth inductive element, the notch circuit coupled in series with the second inductive element, and a second switch coupled in parallel with the fourth inductive element.
