Publication number: 20180287266Abstract: Illustrative embodiments significantly improve RF isolation in a packaged integrated circuit by separating the pins/pads associated with multiple RF channels from one another and also from pins/pads associated with digital circuits. Specifically, in certain exemplary embodiments, the integrated circuit is configured with the pins/pad for the digital circuits on a first edge of the chip, the pins/pads for common RF signals on a second edge of the chip opposite the first edge, and the pins/pads for the individual RF channels on third and fourth edges of the chip. The pins/pads associated with each RF channel may include multiple pins/pads (an “RF group”) and may have a central RF pin/pad with a ground pin/pad on each side of the central RF pin/pad. One or more ground pins/pads may be placed between adjacent RF groups on a given edge of the chip.Type: ApplicationFiled: March 28, 2018Publication date: October 4, 2018Inventors: Kristian N.

Publication number: 20180062274Abstract: In certain exemplary embodiments, register banks are used to allow for fast beam switching (FBS) in a phased array system. Specifically, each beam forming channel is associated with a register bank containing M register sets for configuring such things as gain/amplitude and phase parameters of the beam forming channel. The register banks for all beam forming channels can be preprogrammed and then fast beam switching circuitry allows all beam forming channels across the array to be switched to use the same register set from its corresponding register bank at substantially the same time, thereby allowing the phased array system to be quickly switched between various beam patterns and orientations. Additionally or alternatively, active power control circuitry may be used to control the amount of electrical power provided to or consumed by one or more individual beam forming channels such as to reduce DC power consumption of the array and/or to selectively change the effective directivity of the array.Type: ApplicationFiled: August 31, 2016Publication date: March 1, 2018Inventors: Kristian N.

Publication number: 20170085006Abstract: A phased array includes a laminar substrate having both 1) a plurality of elements forming a patch phased array, and 2) a plurality of integrated circuits. Each integrated circuit is configured to control receipt and transmission of signals by the plurality of elements in the patch phased array. The integrated circuits also are configured to operate the phased array at one or more satellite frequencies—to transmit signals to and/or receive signals from a satellite. Each integrated circuit physically couples with one corresponding element so that incoming signals are received by the corresponding element in a first polarization, and outgoing signals are transmitted by the corresponding element in a second polarization. The phased array isolates the transmit signals from the receive signals by orienting the first and second polarizations differently.Type: ApplicationFiled: September 16, 2016Publication date: March 23, 2017Inventors: David W.
