Technical Examples
  1. Shared-current electronic systems (120, 130, 140, 150, 160, 170, 180, 190, and 200) include two or more solid-state electronic devices, such as a solid-state amplifying device (Q1), a baseband processor (110), and a multiplier/up-converter (112), that are connected in dc series or dc series-parallel, that may be connected in rf series, and that either fixedly or variably share percentages of a dc source voltage. Various embodiments produce separate rf outputs, variably shift the phase of a single rf output, variably shift rf power between/among rf outputs, or produce a frequency-compressed modulation. The apparatus includes means (122, 162, 162A, and /or 162B) for precisely proportioning percentages of the regulated dc source voltage to the dc series-connected electronic devices irrespective of production variations in operating parameters of the electronic devices and/or drift of the electronic devices.
