Menlo Micro addresses design, test and measurement needs for 5G and broadband wireless RF systems with the MM5140

07 August 2023

Menlo Microsystems, Inc. (Menlo Micro) has announced 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 (NR) sub-6 GHz radio frequency (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 +90dBm IP3 linearity, 25W CW RF power handling, ultra-low insertion loss, integrated charge pump with Serial Peripheral Interface (SPI) and General Purpose Input Output (GIPO) interface control, and 3 billion cyclesMM5140 on an evaluation kit board.

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 LGA package, eliminating the need for external components, simplifying customer layouts and reducing bill of materials 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.

Leading 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.
