RF receiver with adjustable antenna assembly
First Claim
1. A radio frequency (RF) receiver comprises:
- an antenna assembly coupled to receive an inbound RF signal, wherein the inbound RF signal includes a first signal component and a second signal component, wherein the antenna assembly adjusts at least one of amplitude and phase of at least one of the first and second signal components to produce an adjusted inbound RF signal based on an adjust signal;
a low noise amplifier module coupled to amplify the adjusted inbound RF signal to produce an amplified inbound RF signal;
a down conversion module coupled to convert the amplified inbound RF signal into a first inbound symbol stream corresponding to the first signal component and into a second inbound symbol stream corresponding to the second signal component; and
a baseband processing module coupled to convert the first and second inbound symbol streams into inbound data and to generate the adjust signal.

Abstract
A radio frequency (RF) receiver includes an antenna assembly, a low noise amplifier module, a down conversion module, and a baseband processing module. The antenna assembly is coupled to receive an inbound RF signal that includes a first signal component and a second signal component. The antenna assembly adjusts amplitude and/or phase of the first and/or second signal components to produce an adjusted inbound RF signal based on an adjust signal. The low noise amplifier module amplifies the adjusted inbound RF signal to produce an amplified inbound RF signal. The down conversion module converts the amplified inbound RF signal into a first inbound symbol stream corresponding to the first signal component and into a second inbound symbol stream corresponding to the second signal component. The baseband processing module converts the first and second inbound symbol streams into inbound data and to generate the adjust signal.
