摘要： In an exemplary embodiment, a phased array antenna comprises multiple subcircuits in communication with multiple radiating elements. The radio frequency signals are adjusted for both polarization control and beam steering. In a receive embodiment, multiple RF signals are received and combined into at least one receive beam output. In a transmit embodiment, at least one transmit beam input is divided and transmitted through multiple radiating elements. In an exemplary embodiment, the phased array antenna provides multi-beam formation over multiple operating frequency bands. The wideband nature of the active components allows for operation over multiple frequency bands simultaneously. Furthermore, the antenna polarization may be static or dynamically controlled at the subarray or radiating element level.

摘要： In various embodiments, an active vector generator may comprise a vector component switch and a first amplitude adjustment component in parallel with a second amplitude adjustment component. The first and second amplitude adjustment components may operate with different ranges of amplitude. For example, the first amplitude adjustment component may have a full range of amplitude and the second amplitude adjustment component may have a partial range of amplitude. The vector component switch may operate to receive two signals and route the signals to the various amplitude adjustment components based on the relative magnitudes of the two signals. A benefit of having two amplitude adjustment components with selectable signal pathways is that the all the phase states may be obtained but using less robust and expensive amplitude adjustment components.

摘要： An automatic gain control device (110) includes a peak detector (202) configured to receive a current output of an ADC (108) and to compare it to a previous output to produce a peak value. The automatic gain control device (110) also includes an out-of-range indicator (204) configured to receive an out-of-range signal if an input to the ADC exceeds the dynamic range of the ADC. The out-of-range indicator (204) increases the peak value if the out-of-range indicator (204) receives the out-of range signal. An error detector (206) is coupled to the out-of-range indicator (204) and the peak detector (202) and produces an error level that is the difference of an output of the out-of-range indicator (204) and a pre-selected target value. The pre-selected target value is chosen to attenuate interference signals that exceed the dynamic range of the ADC (108) but minimizes the attenuation of communication signals. An integrator (208) is coupled to the error detector (206) and sums the error level with an integrator value to determine a new integrator value. A quantizer (210), coupled to the integrator (208), receives the new integrator value and determines a new level of attenuation.
