DPDT switch gives a leg up on AI and ML applications

11 November 2021

Menlo Microsystems has introduced a new double-pole/double-throw (DPDT) switch that provides high performance and data rates for high-speed differential switching applications.

The MM5600 offers a high-speed operation from DC to 20 GHz or 40 Gbps, which the company claims outperforms conventional electromechanical (EM) relays and solid-state switches. The switch allows for double interconnect speeds over the PCIe 4.0 specification and can be configured for single-ended operation for RF and microwave applications.

The switch can be used in next-generation artificial intelligence, machine learning, GPU/CPU, data center and cloud-based applications as well as automated test equipment device interface boards and high-speed computer peripheral interfaces.

The MM5600 also features:

  • Fast switching — With a speeds of less than 10 µs operation time and less than 2 µs release time, about 1,000 times faster than EM relays.
  • Reliability — The switch can operate with more than three billion switching cycles and a 1,000 times longer lifetime compared to conventional EM relays.
  • Compact design — The switch measures 8 mm x 8 mm x 1.6 mm in a QFN package that provides a 90% reduction in size over conventional EM relays.
  • Power efficiency — The switch operates at less than 0.08 mW, a 99% reduction in power consumption compared to EM relays.
  • Leading IP3 linearity — The MM5600 achieves an IP3 linearity of more than 90 dBm with a power handling capability of 33 dBm, enabling large reductions in distortion and delivering up to a 10,000 times improvement over existing EM relays and solid-state switches.
