摘要： A phased array antenna may include a substrate and at least one phased array antenna element carried thereby, at least one element controller for controlling the at least one phased array antenna element based upon desired compensation data, and a central controller for supplying to the at least one element controller a current value of a quick control parameter and a block of current compensation data. The block of current compensation data may be based upon a current value of a slow control parameter and a range of possible values for the quick control parameter. Further, the quick control parameter may vary more quickly than the slow control parameter. Additionally, the at least one element controller may determine the desired compensation data based upon the supplied block of current compensation data and the current value of the quick control parameter.

摘要： A temperature sensor may include a capacitor, a circuit element coupled in series with the capacitor and having a resistance that varies with temperature, and a controller. The controller is for charging/discharging the capacitor through the circuit element, measuring a charging/discharging time required to charge/discharge the capacitor to a predetermined threshold, and determining a temperature based upon the charging/discharging time. More specifically, the circuit element may be a thermistor, for example. The temperature sensor may further include at least one calibration resistor coupled between the controller and the capacitor. As such, the controller may sequentially charge/discharge the capacitor through the circuit element and the at least one calibration resistor, measure respective charging/discharging times required to charge/discharge the capacitor to the predetermined threshold through the circuit element and the at least one calibration resistor, and determine the temperature based upon the charging/discharging times.
