  • Patent number: 10250194
    Abstract: An envelope tracking scheme can be used, such as to modulate a supply node of a power amplifier circuit to improve efficiency. For example, a magnitude or amplitude envelope of a signal to be modulated can be scaled and used to drive a node, such as a drain, of the power amplifier circuit. An envelope tracking signal can be generated such as having a bandwidth that is compressed as compared to a full-bandwidth envelope signal. A peak-value “look ahead” technique can be used, for example, so that amplitude compression or clipping of the transmit signal is suppressed when the bandwidth-compressed envelope tracking signal is used to modulate a supply node of the power amplifier used to amplify the transmit signal.

  • Patent number: 10243519
    Abstract: Various methods and circuital arrangements for biasing one or more gates of stacked transistors of an amplifier are presented, where the amplifier can have a varying supply voltage that varies according to a control voltage. The control voltage can be related to a desired output power of the amplifier and/or to an envelope signal of an input signal to the amplifier. Particular biasing for selectively controlling the stacked transistors to operate in either a saturation region or a triode region is also presented. Benefits of such controlling, including increased linear response of an output power of the amplifier, are also discussed.

  • Patent number: 10230207
    Abstract: A connector removal tool comprising a rigid press and release device for removing a connector from an electronics assembly. Upon engagement of the rigid press and the release device, first and second press members of the rigid press engage and move about a pair of deflecting engagement members of the release device to cause the pair of deflecting engagement members to deflect to compress and unlock interlocking tabs of the connector to facilitate removal from the electronics assembly. A single motion of the rigid press can cause unlocking of the connector. Alternatively, a connector removal tool comprises biased deflecting rigid press members that engage directly with a connector to unlock the interlocking tabs of the connector to facilitate removal of the connector from an electronics assembly.
