Dynamic RF front end
First Claim
1. A dynamic radio frequency (RF) front end comprises:
- a power amplifier structure configured to generate a plurality of outbound RF signals from one outbound RF signal, wherein the power amplifier structure includes a transmit phase selection module to receive a first selection signal to set a transmit phase for the plurality of outbound RF signals based on a transmit phase rotation, in which the power amplifier structure is to provide the plurality of outbound RF signals to corresponding antennas of an antenna array, wherein the corresponding antennas of the antenna array have an orthogonal arrangement, for transmission of the plurality of outbound RF signals using a first circular polarization which is one of clockwise or counter-clockwise polarization; and
a low noise amplifier structure configured to receive a plurality of inbound RF signals from the corresponding antennas of the antenna array using a second circular polarization that is opposite in clockwise or counter-clockwise polarization from the first circular polarization, in which the plurality of inbound RF signals have different receive phase relationship based on the orthogonal arrangement of the corresponding antennas, wherein the low noise amplifier structure includes a receive phase selection module to receive a second selection signal to select and output a selected one of the plurality of inbound RF signals as a selected inbound RF signal that provides a favorable phase relationship with respect to the one outbound RF signal, the first and second selection signals to be generated by a control module that determines the favorable phase relationship, wherein the opposite polarization and the favorable phase relationship reduces interference between the selected inbound RF signal and the one outbound RF signal.

Abstract
A dynamic radio frequency (RF) front end includes an antenna array, a power amplifier structure, and a low noise amplifier structure. The power amplifier structure generates a plurality of outbound RF signals from an outbound RF signal and provides the plurality of outbound RF signals to the antenna array. Each of the plurality of outbound RF signals has a different transmit phase rotation. The low noise amplifier structure receives a plurality of inbound RF signals from the antenna array and outputs one of the plurality of inbound RF signals based on a favorable phase relationship with respect to the outbound RF signal. Each of the plurality of inbound RF signals has a different receive phase rotation.
