Single-chip MEMS 5 × 5 and 20 × 20 double-pole single-throw switch arrays for automating telecommunication networks

Abstract: This paper reports on microelectromechanical (MEMS) switch arrays with 5 × 5 and 20 × 20 double-pole single-throw (DPST) switches embedded and packaged on a single chip, which are intended for automating main distribution frames in copper-wire telecommunication networks. Whenever a customer requests a change in his telecommunication services, the copper-wire network has to be reconfigured which is currently done manually by a costly physical re-routing of the connections in the main distribution frames. To red… Show more

“…For some switching applications, such as radar signal encoding, MEMS switches are too slow anyway since switching times of nanoseconds are required. In contrast to that, for many applications, such as the automated reconfiguration of telecommunication networks [54], an application which has attracted increased attention of the RF MEMS community, any MEMS switch with subsecond switching time is fast enough. Also, it should be noted that the switching time of the present switch concept is still by a factor of ten times faster than electrothermally actuated MEMS switches.…”

“…Aside from that, actuator arrays are also employed for cross-connect switches, which enable the automated interconnection of a number of input channels to a number of output channels in any permutation desired. There are reports on microactuator arrays for both optical [8], [9] and electrical [10] cross connects.…”

“…The proposed switch as a demonstrator was developed for proof of concept, focusing on the possible improvement in the performance of MEMS switch by employing closured diaphragm and perforated base-substrate. However, the proposed switch still can find some applications, such as the automated re-configuration of telecommunication networks [113], an application which has attracted increased attention of the RF MEMS community, any MEMS switch with sub-second switching time is fast enough. It should be mentioned that the proposed switch design can be scaled down in size.…”
