MM5140 from MENLO MICRO is a single-pole/four-throw (SP4T) Dc-to-6GHz switch. MM5140 is capable of handling 25W of power with a low insertion loss of 0.2dB at 3GHz. It is suitable for applications requiring high reliability such as antenna tuning, beam-steering types of equipment in 5G base, and other high-power RF switching applications.

The MM5140 is built on the company’s Ideal Switch technology, and the company claims that this switch can outperform the electromechanical relays (EMRs) and conventional solid-state switches. The switch features a built-in high voltage charge pump embedded in a 5.2mm x 4.2mm LGA package, therefore, eliminating the need for external components. The integrated charge pump circuit offers both flexible SPI and GPIO digital interfaces, enabling easy control from any host processor or test system.

“The MM5140 switch eliminates the compromises developers often face when deciding between electromechanical relays or solid-state switches for RF designs,” said Chris Giovanniello, co-founder and SVP marketing, Menlo Micro. “Ideal Switch technology enables the MM5140 to outperform EMRs across all application-critical metrics while offering the size, reliability, and speed benefits of a solid-state switch. Following the success of our MM5130, MM5600, and MM5120 products, we are excited to be bringing yet another high-performance Ideal Switch to the market.”

Menlo also claims that the MM5140 helps RF developers achieve massive reductions in cost, size, weight, and power loss, and the switch has an operating lifetime of more than 3 billion switching cycles with no degradation in performance. The switch is designed to work over a wide temperature range from -40C to +85C and has superior linearity from DC to 6 GHz.

The SP4T switch is suitable for applications in defense and aerospace, wireless infrastructure, and use in test and measurement equipment. The production release of the MM5140 is scheduled for Q2 2022 while the sample switches have been made available.
