Abstract: Certain aspects of the present disclosure generally relate to circuitry and techniques for digital-to-analog conversion. One example system for digital-to-analog conversion generally includes a first digital-to-analog converter (DAC) having an input coupled to an input node of the system and a mixing-mode DAC having an input coupled to an input node of the system. The mixing-mode DAC may include a second DAC and a mixer, an output of the second DAC being coupled to an input of the mixer. The system may also include a combiner, wherein an output of the first DAC is coupled to a first input of the combiner, and wherein an output of the mixer is coupled to a second input of the combiner.

Abstract: Tunable MEMS resonators having adjustable resonance frequency and capable of handling large signals are described. In one exemplary design, a tunable MEMS resonator includes (i) a first part having a cavity and a post and (ii) a second part mated to the first part and including a movable layer located under the post. Each part may be covered with a metal layer on the surface facing the other part. The movable plate may be mechanically moved by a DC voltage to vary the resonance frequency of the MEMS resonator. The cavity may have a rectangular or circular shape and may be empty or filled with a dielectric material. The post may be positioned in the middle of the cavity. The movable plate may be attached to the second part (i) via an anchor and operated as a cantilever or (ii) via two anchors and operated as a bridge.

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.
