  • Patent number: 6898420
    Abstract: An apparatus and method for eliminating interference caused by spurious signals in communication signals communicated via a communication device on any one of a plurality of different channels, the communication device operating at a rate set by a system clock signal. The system clock frequency is generated at a first frequency, the first frequency generating spurious signals on at least one of the different channels. The system clock frequency is toggled by a first predetermined amount to a second frequency when the communication device is to be tuned to one of the different channels so as to remove the spurious signals from the tuned channel. The communication device is tuned to the at least one of the different channels. A return of the timing error to a predetermined value is synchronized at a start of a receive data capture event.

  • Patent number: 6836249
    Abstract: An antenna assembly for a mobile communication device. The antenna assembly can include a RF connection feed point and a planar radiating element including a conductive area split by a nonconductive gap which divides the planar radiating element into a first arm having an end coupled to the RF connection feed point and a second arm having an end coupled to the RF connection feed point. The antenna assembly can also include a first connection point coupled to the opposite end of the first arm from the RF connection feed point, the first connection point being selectively coupled to an impedance.
