An RF receiver section includes an adjustable antenna assembly, a low noise amplifier module, and a down conversion module. The method includes a communication device that receives a plurality data frames, wherein the communication device is capable of ascertaining the beginning of an information portion within the received frames. A transverse blade is mounted in one shell, and a cutting support is mounted in the other shell across from the blade. The semiconductor diode includes a channel region of a second conductivity type electrically coupled to the first terminal, wherein a bottom of the channel region adjoins the first semiconductor region. The optimization control circuit controls an equalizer control signal that is for adjusting characteristics of the equalizer circuit and a driver control signal that is for adjusting characteristics of the pre-emphasis driver circuit and sets the equalizer control signal and driver control signal so that the operational margin of the clock and data recovery circuit is maximized.
