    摘要: RF PA circuitry and a DC-DC converter, which includes an RF PA envelope power supply and DC-DC control circuitry, are disclosed. The PA envelope power supply provides an envelope power supply signal to the RF PA circuitry. The DC-DC control circuitry has a DC-DC look-up table (LUT) structure, which has at least a first DC-DC LUT. The DC-DC control circuitry uses DC-DC LUT index information as an index to the DC-DC LUT structure to obtain DC-DC converter operational control parameters. The DC-DC control circuitry then configures the PA envelope power supply using the DC-DC converter operational control parameters. Using the DC-DC LUT structure provides flexibility in configuring the DC-DC converter for different applications, for multiple static operating conditions, for multiple dynamic operating conditions, or any combination thereof.

    摘要: A split current current digital-to-analog converter (IDAC) and a radio frequency (RF) power amplifier (PA) stage are disclosed. The split current IDAC operates in a selected one of a group of DDS operating modes and provides a group of array bias signals based on the selected one of the group of DDS operating modes. Each of the group of array bias signals is a current signal. The RF PA stage includes a group of arrays of amplifying transistor elements. The RF PA stage biases at least one of the group of arrays of amplifying transistor elements based on the group of array bias signals. Further, the RF PA stage receives and amplifies an RF stage input signal to provide an RF stage output signal using at least one of the group of arrays of amplifying transistor elements that is biased.
