    Abstract: A dynamically varying linearity system "DVLS" capable of varying the linearity of a radio frequency (RF) front-end of a communication device responsive to receiving a condition signal indicating a desired mode of operation of a transmitter. The DVLS may include a condition signal indicative of the desired mode of operation and a controller that adjusts the linearity of the transmitter responsive to the condition signal. The condition signal may be responsive to a user interface. The controller, responsive to the condition signal, may dynamically adjust the operating current of the transmitter.

    Abstract: A local oscillator circuit for generating a local frequency signal is provided. The local oscillator circuit may cooperate with a radio circuit for providing wireless reception or transmission. The radio circuit performs modulation or demodulation processes with reference to a defined carrier signal frequency. The local oscillator circuit has a voltage controlled oscillator that generates a VCO signal at frequency different than the carrier frequency. A frequency scaling circuit applies a scaling factor to the VCO signal, with the scaled signal generated at the frequency of the defined carrier frequency.

    Abstract: A receiver for a multi-mode wireless device is provided. The receiver has multiple analog RF front end modules, with each module supporting a different mode of operation. The receiver has a single digital backend module for generating a digital baseband signal. A controller selects one of the available RF modules to use, and the selected RF module provides an analog communication signal to the digital backend. Each available mode has an associated set of factors. When a particular mode is selected, the set of factors associated with the selected mode is provided to the digital backend. The digital backend uses these factors to adjust the processing characteristics of its components, such as its analog to digital converter, filters, and gain controller. In this way, the single digital backend is adaptable to the requirements of each of the available radio modes.

    Abstract: A multi-band communication device configured with a mobile communication device for voice or data communication over a cellular, satellite or other communication network and configured with an auxiliary communication system configured to receive and/or transmit an auxiliary communication signal. The mobile communication device and auxiliary communication system are integrated into the same components within the multi-band communication device thereby allowing the components to share the processing tasks associated with each communication device within the multi-band communication device. The auxiliary communication device may be configured to operate during standby mode of the mobile communication device, such as during reception of a paging signal. The auxiliary communication device may comprise, but is not limited to, AM or FM radio, personal communication devices such as FRS, GMRS, or weather band radio.
