Abstract: A radio transceiver including a transmitter and a receiver. A filter coupled to an output of the transmitter, the filter has one or more inductors and one or more capacitors, where the filter is tuned by varying one or more capacitance values of the one or more capacitors in the filter to tune the filter. The one or more capacitors are Barium Strontium Titanate (BST) ceramic integrated capacitors that are each tuned by application of a bias voltage thereto. A filter tuner circuit is configured to apply the bias voltage to the one or more capacitors, where the bias voltage is initially established as a stored initial value, and where the bias voltage is refined by a proportional-integral-derivative (PID) controller configured to optimize a power within the transceiver. This abstract is not to be considered limiting since various implementations may incorporate more, fewer or different elements.

Abstract translation: 包括发射机和接收机的无线电收发机。 滤波器耦合到发射机的输出端，滤波器具有一个或多个电感器和一个或多个电容器，其中滤波器通过改变滤波器中的一个或多个电容器的一个或多个电容值来调谐，以调谐滤波器。 一个或多个电容器是通过施加偏置电压来调整的钡钡酸钡（BST）陶瓷集成电容器。 滤波器调谐器电路被配置为将偏置电压施加到一个或多个电容器，其中偏置电压最初被建立为存储的初始值，并且偏置电压由比例积分微分（PID）控制器精调 以优化收发器内的功率。 该摘要不被认为是限制性的，因为各种实现可以包含更多，更少或不同的元素。
