FIELD: power amplifiers.
SUBSTANCE: power amplifier includes a two-dimensional matrix with size N × M active cells, formed by successive stacking of main electrodes of several active cells. Stacks are connected in parallel to form a two-dimensional matrix. Power amplifier includes a control structure for coordinating control of active cells such that the effective output power of the two-dimensional matrix is approximately N × M output power of each active cell.
EFFECT: technical result consists in improvement of reliability.
