Abstract: An electronic device may include processing circuitry having a first impedance coupled to a first circuit board, where the electronic device uses the processing circuity to generate one or more radio frequency signals. The electronic device may also include power circuitry to amplify the one or more radio frequency signals, where the power circuitry is coupled to a second circuit board. An interposer may be disposed between the first circuit board and the second circuit board. The interposer may include a via structure having a characteristic impedance to match the first impedance and the second impedance, where the via structure may transmit the one or more radio frequency signals through the interposer between the processing circuitry and the power circuitry.

Abstract: Devices and methods for dynamically selecting a matching network for an antenna are provided. In one example, an electronic device capable of selecting such a matching network may include an antenna, several selectable matching networks, a radio receiver, and matching network control circuitry. The radio receiver may couple to the antenna via one of the selectable matching networks to receive a radio signal with both an analog and digital component. The matching network control circuitry may select the matching network from among the several selectable matching networks based at least in part on a characteristic of the digital component of the radio signal.
