ABSTRACT:
A channelization filter communication system comprises: a channelization filtering system, a calibration unit, amplifiers, communication channel frequency converters and a baseband processor. The channelization filtering system includes a selector input configured to receive a communication channel filter selector signal and selectable communication channel filter elements. The selectable communication channel filter elements include one or more resistors formed of a first resistor type and one or more capacitors formed of a first capacitor type. The calibration unit includes a calibration signal generator configured to provide a calibration signal and a frequency measurement unit. The calibration signal generator includes one or more resistors formed of the same first resistor type and one or more capacitors formed of the same first capacitor type. The frequency measurement unit includes a first input configured to receive the calibration signal and an output configured to provide information representing the frequency of the calibration signal.
