Abstract
A high-power limiter comprising silicon PIN diodes for millimeter waves is formed by a waveguide associated with a silicon substrate wherein is formed a matrix of PIN diodes. The PIN diodes are formed throughout the thickness of the silicon substrate.
Claims5
A high-power limiter comprising:
- a rectangular waveguide having a longitudinal axis (.DELTA.), having dimensions permitting propagation of millimeter waves,
- a silicon substrate of parallelepipedic form and rectangular cross-section substantially of the same dimensions as those of the cross-section of the guide, installed in the guide transversely to the longitudinal axis of the same,
- a series-parallel array of silicon PIN diodes of the same dimensions, produced in the surface of the substrate, the diodes being situated facing the input of power into the guide, and the dimension of the silicon substrate along the longitudinal axis (.DELTA.) of the waveguide being equal to that of the silicon area I of each of the PIN diodes along the same axis (.DELTA.).
