Abstract:
The RF MEMS crosspoint switch (1) comprising a first transmission (10) line and a second transmission line (11) that crosses the first transmission line ; the first transmission line (10) comprises two spaced-apart transmission line portions (100, 101), and a switch element (12) that permanently electrically connects the said two spaced-apart transmission line portions (100, 101) ; the second transmission line (11) crosses the first transmission line (10) between the two spaced-apart transmission line portions (100, 101); the RF MEMS crosspoint switch (1) further comprises actuation means (121) for actuating the switch element (12) at least between a first position, in which the switch element (12) is electrically connecting the said two spaced-apart transmission line portions (100, 101) of the first transmission line (10) and the first (10) and second (11) transmission lines are electrically disconnected, and a second position, in which the switch element (12) is electrically connecting the said two spaced-apart transmission line portions (100, 101) of the first transmission line (10) and is also electrically connecting the two transmission lines (10, 11) together.
Abstract:
The MEMS fixed capacitor (1) comprises a bottom metal electrode (3) formed onto a substrate (S), a top metal electrode (2) supported by metal pillars (5) above the bottom metal electrode, and a gas-containing gap (4) forming a non-solid dielectric layer between said top (2) and bottom (3) metal electrodes ; the distance (D) between the top (2) and bottom (3) metal electrodes is not more than 1µm and the thickness (E) of the top metal electrode (2) is not less than 1µm.
