  • Operating parameter control for a power amplifier
    Patent number: 9088260
    Abstract: A method of controlling operating parameters of a radio frequency power amplifier amplifying an input signal applied in bursts with controlled input power to an input of the power amplifier, comprising responding to gain variation parameters relating to variations in the scalar gain of said amplifier starting during an initial ramp-up period of a first burst to control supply voltage and quiescent current parameters for said amplifier during a subsequent burst.
    Type: Grant

    Assignee: Freescale Semiconductor, Inc.
    Inventors: Francois Dupis, Jacques Trichet
  • Test unit for testing the frequency characteristic of a transmitter
    Patent number: 8311494
    Abstract: A test unit for testing the frequency characteristics of one or more components of a transmitter of modulated signals. The test unit includes a data source for generating a test pattern of data. A test unit output is connected to the data source and connectable to an input of one or more of the components, for inputting the test pattern of data to the one or more components. The test unit includes a memory in which a first predetermined data sequence and a second predetermined data sequence are stored. The data source is connected with an data input to the memory, and the data source is arranged to generating the test pattern of data including the predetermined data sequences.
