Menlo Microsystems has announced a new double-pole/double-throw (DPDT) switch providing high performance and data rates for high-speed differential switching applications. Based on the company’s market-proven Ideal Switch technology, the new MM5600 offers high-speed operation from DC to 20 GHz or 40 Gbps, significantly outperforming conventional electromechanical (EM) relays and solid-state switches, according to Menlo. The switch’s flexible configuration also enables internal differential crossover capabilities, greatly simplifying board routing.
The MM5600 provides an advanced differential switching solution for high-speed digital applications based on the latest PCI Express standard, PCIe Gen 5, which doubles interconnect speeds over the PCIe 4.0 specification (32 gigatransfers per second (GTps) versus 16 GTps). Faster PCIe speeds are essential for next-generation artificial intelligence (AI), machine learning (ML), 5G infrastructure, data centre and cloud-based applications, as well as automated test equipment (ATE) device interface boards and high-speed computer peripheral interfaces. The MM5600 can also be configured for single-ended operation for RF and microwave applications.
This DPDT switch provides high reliability and can operate for more than three billion switching cycles, resulting in reduced downtime, maintenance and cost and a 1000x longer lifetime compared to conventional electromagnetic relays. Its low-profile, small-footprint (64 mm2) design in an 8 x 8 x 1,6 mm QFN package also provides a large comparative reduction in size. This significant volume reduction enables more parallel tests and easier top and/or bottom routing.
The MM5600 operates at less than 0,08 mW, with an integrated driver that offers two modes of operation and can be controlled through a serial or parallel interface to drive the switch’s high-voltage gate lines. The switch is designed with full electrostatic discharge (ESD) protection on all input/output ports.
The device achieves an IP3 linearity of more than +90 dBm with a power handling capability of +33 dBm, enabling large reductions in distortion. IP3 is the figure of merit in determining how much distortion a switch will introduce into a system, impacting the quality of transmitted or received signals.
