High linearity, low insertion loss SP4T switches introduced

25 August 2022

Menlo Microsystems Inc. has launched two switches that provides high linearity and ultra-low insertion loss designed for integration for radiofrequency (RF) switching applications, 5G network infrastructure and test and measurement equipment.

The SP4T switches provide more than three billion switching cycles for a longer lifespan compared to traditional EMRs. Source: Menlo Microsystems.

The MM5120 single-pole/four-throw (SP4T) DC-to-18 GHz switch and the MM5140 DC-to-6 G Hz SP4T switch offer 25 W power handling and outperform electromechanical relays (EMRs) and conventional solid-state switches. Both switches feature integrate charge pump and driver circuit with SPI and GPIO interface control options.

Menlo Microsystems said the switches will allow makers of 5G infrastructure and test and measurement equipment to reduce the cost and complexity of applications while also having new ways to create electronic designs.

The SP4T switches can operate with more than three billion switching cycles, resulting in reduced downtime, maintenance and cost. Also, it provides a 1,000 x longer lifetime compared to conventional EMRs, the company said.

Other features of the switches include:

  • Operation of less than 10 mW.
  • IP3 linearity of 90 dBm.
  • Small footprint with a custom-designed, built-in high-voltage charge pump/driver circuit.
