Abstract: Disclosed is a sheet resistor designed to operate in a high frequency environment. Unlike conventional sheet resistors, the equivalent series inductance (ESL) is minimized or even eliminated altogether when using the designed sheet resistor. As a result, better signal isolation can be achieved.

Abstract: A device that includes a first board, a second board, and coaxial cable coupled to the first board and the second board. The coaxial cable includes a multi-line coaxial cable configured to provide at least two electrical paths for electrical currents between the first board and the second board. A first plug is coupled to the first board. A second plug is coupled to the second board. The coaxial cable includes a first receptable and a second receptable. The first receptable is configured to couple to the first plug. The second receptable is configured to couple to the second plug. The coaxial cable is configured to provide (i) a first electrical path for a first electrical current between the first board and the second board, and (ii) a second electrical path for a second electrical current between the first board and the second board.

Abstract: Certain aspects of the present disclosure provide techniques for training a digital pre-distorter (DPD) using real-time over-the-air transmissions and receptions by a user equipment (UE). A method for training the DPD generally includes transmitting a signal, generated by a transmitter front end, via a first port; sampling the signal, received over the air, at a second port; performing signal processing cleaning (e.g., synchronization, linear over-the-air channel estimation and equalization); calculating coefficients for a DPD; and configuring the DPD with the coefficients, for use in digitally pre-distorting sub sequent transmissions.

Abstract: An antenna is provided that includes a dielectric-filled cavity having a bottom surface, a top surface, and a rectangular perimeter. A round metal layer faces the bottom surface whereas a resonator metal layer faces the top surface. A plurality of metallic vias is arranged about the rectangular perimeter to couple a perimeter of resonator layer to the ground layer. An opening divides the resonator layer into a first pair of resonators and into a second pair of resonators. Within each pair of resonators, one resonator is configured for operation according to a first linear polarization whereas a second resonator is configured for operation according to a second linear polarization that is orthogonal to the first linear polarization.

Abstract: Disclosed is an antenna on glass (AOG) device having an air cavity at least partially formed in a photosensitive glass substrate. An air cavity structure is at least partially encloses the air cavity and wherein the air cavity structure at least partially formed from the photosensitive glass substrate. An antenna is formed from portion of a top conductive layer disposed on a top surface of the air cavity structure and at least partially overlapping the air cavity. A metallization structure is provided having a bottom conductive layer disposed on a bottom surface of the air cavity structure, wherein the bottom conductive layer is electrically coupled to the top metal layer by a conductive pillar disposed through the photosensitive glass substrate. In addition, the AOG device may integrate one or more MIM capacitors and/or inductors that allow for RF filtering and impedance matching.
