    摘要： A modular radio frequency (RF) device includes N base units, each including a differential segmented array (DSA) tile with a support board and a two-dimensional (2D) array of electrically conductive tapered projections disposed on the support board. Neighboring pairs of the electrically conductive tapered projections form RF pixels. The N DSA tiles are arranged to form an RF aperture. The N base units are programmed to switch the RF aperture between a first operating mode and a second operating mode. In the first operating mode, the N base units are operated as at least two independent subsets with each subset operating as an RF transmitter or receiver independently of the other subsets. In the second operating mode all N base units coherently combine as a single phased array RF transmitter or receiver.

    摘要： A radio frequency (RF) aperture includes an interface printed circuit board. An array of electrically conductive tapered projections have bases disposed on a front side of the interface printed circuit board and extend away from the front side of the interface printed circuit board. Chip baluns are mounted on the back side of the interface printed circuit board. Each chip balun has a balanced port electrically connected with two neighboring electrically conductive tapered projections via electrical feedthroughs passing through the interface printed circuit board. Each chip balun further has an unbalanced port, and RF circuitry disposed at the back side of the interface printed circuit board is electrically connected with the unbalanced ports of the chip baluns. The electrically conductive tapered projections include dielectric tapered projections and an electrically conductive layer disposed on an inner or outer surface of the dielectric tapered projections.
