Menlo Microsystems, Inc. announced a product specifications update for the MM5140 DC-to-8 GHz SP4T switch. This product is positioned to address the globally evolving wireless standards in 5G New Radio sub-6 GHz RF network applications and emerging broadband wireless applications up to 8 GHz, which includes the ever-growing O-RAN frequency bands. 

Built on Menlo Micro’s market-proven Ideal Switch technology, the MM5140 continues to offer +90 dBm IP3 linearity, 25 W CW RF power handling, ultra-low insertion loss, integrated charge pump with Serial Peripheral Interface and General Purpose Input Output interface control and 3 billion cycles reliability, all in a 5.2 mm x 4.2 mm LGA package. 

“Global and emerging wireless network equipment and component designers are constantly seeking new and innovative ways to design for state-of-the-art performances while delivering economies at scale and cost,” said Chris Giovanniello, co-founder and senior vice president of marketing at Menlo Micro. “The MM5140’s specifications enable designers to meet their product and testing performance needs with efficient design, while creating better OPEX and a rapid time-to-market.”

Reliability: The SP4T switch provides unmatched reliability and can operate with more than three billion switching cycles, resulting in reduced downtime, maintenance and cost and a significantly longer lifetime when compared to conventional electro-mechanical relays (EMRs).

Compact design: The MM5140’s small-footprint/low-profile design features a custom-designed, built-in high-voltage charge pump/driver circuit integrated into a miniature 5.2 x 4.2 mm LGA package, eliminating the need for external components, simplifying customer layouts and reducing BOM cost.

Power efficiency: The SP4T switch operates at less than 15 mW, reducing power consumption when compared to EMRs, making them the most energy efficient broadband SP4T switches available.

IP3 linearity: The MM5140 features best-in-class IP3 linearity of +90 dBm, enabling significant reductions in distortion, which is critical for applications such as beam-steering antennas used in 5G network infrastructure. IP3 is a figure of merit in determining how much distortion a switch will introduce into a system, impacting the quality of transmitted or received signals.
