MEMS DPDT switch reduces power, size at 20GHz, 40Gbps
The MM5600 double-pole, double-throw MEMS switch outperforms electromechanical relays and solid-state switches in terms of size and power consumption, according to manufacturer Menlo Microsystems Inc.

Operating from dc to 20GHz for analog signals and up to 40Gbps the MM5600 offers a 99 percent power reduction and 90 percent size reduction compared with traditional equivalents, the company claimed. The MM5600 switch’s flexible configuration also enables internal differential crossover capabilities, greatly simplifying board routing.

The MM5600 supports differential switching for faster PCIs boards used for artificial intelligence (AI), machine learning (ML), 5G infrastructure, data center and cloud-based applications, as well as automated test equipment (ATE) device interface boards and high-speed computer peripheral interfaces. The MM5600 switch also can be configured for single-ended operation for RF and microwave applications.

"Existing electromechanical relays and semiconductors fall short in meeting the extreme performance requirements of PCIe Gen 5 and other high-speed data interfaces such as InfiniBand, USB4, and 112G Ethernet," said Chris Giovanniello, co-founder and senior vice president of marketing at Menlo Micro, in a statement.

The MM5600 achieves an IP3 linearity of more than 90dBm with a power handling capability of 33dBm. It has 10 microsecond operation time and 2 microsecond release time, about 10^4 times faster than EM relays. The MEMS switch is rated for 3 billion cycles. The switch consumes 0.08mW and comes in an 8mm by 8mm by 1.6mm QFN package.

The MM5600 DPDT differential switch is sampling.
