摘要： A power ramping circuit for use in the transmit path of a radio frequency (RF) circuit. The power ramping circuit includes parallel connected transistors used as logarithmic resistor attenuators for adjusting current to a mixer circuit in the transmit path. The parallel connected transistors can be sized differently, and are sequentially turned off to gradually increase the current provided to the mixer circuit. A ramp control circuit controls the parallel connected transistors in response to either an analog signal or a digital signal.

摘要： The invention provides a system and method of generating a number of inputs to the mixer elements in a direct conversion (homodyne) receiver configuration using Virtual Local Oscillator (VLO) techniques. These generated inputs meet the requirement that they must have a fixed and stable phase-relationship, as well as being correctly related in terms of their power spectra relative to the operating radio (RF), intermediate (IF), and baseband frequencies of the system, and that when applied to the mixer elements they permit the mixer elements to create internally the effect of applying the Local Oscillator signal at a suitable frequency.

摘要： Function approximation circuitry approximates an arbitrary function F over discrete inputs. Discrete values of the function F are stored in a lookup table (LUT) component for various inputs. An addressing module generates an address from an input. An interpolation factor module generates an interpolation factor from the input. An interpolation module generates an output, which is an approximate value of the function F for the input, from the interpolation factor, and from outputs of the LUT component when the LUT component is addressed by the address.

摘要： Peripheral components of a wireless radio system can be controlled by a wireless transceiver. The transceiver stores parallel or serial bit patterns in memory, each bit pattern corresponding to a particular control configuration for one or more peripheral components. A further control device, such as baseband controller, issues an address corresponding to the desired functional operation of the peripheral components to the transceiver. A memory sub-system of the transceiver uses the address to output the appropriate bit pattern. The bit pattern can be provided in parallel to statically control individual control lines, or can be converted into a serial bitstream decodable by a command decoder. The command decoder can then decode the bitstream and locally issue the appropriate control signals for the peripheral components.

摘要： A method for controlling a transmitter power control system in communication networks that include a modulation scheme having a non-constant amplitude envelope. The method includes generating a transmission signal and transitioning the transmission signal from a first specified power level to a second specified power level and having a transition period therebetween, and generating a constant amplitude envelope modulation of the transmission signal during the transition period. The method may further include generating a non-constant amplitude envelope modulation of the transmission signal at the first specified power level, switching to the constant amplitude envelope modulation of the transmission signal during the transition period and generating the non-constant amplitude envelope modulation of the transmission signal at the second specified power level. A mobile communication device may be used to perform the method.
