The switch aims to replace electromechanical relays (EMRs) and conventional solid-state switches in applications requiring reliability such as antenna tuning and beam-steering equipment used in 5G base stations. The rapid rollout of 5G services worldwide is driving ever-increasing demand for sub-6 GHz connectivity, especially in the coveted C-band spectrum. Emerging mid-band 5G networks with advanced beamforming antennas also require reliable, high-performance RF switching technology.

MM5140具有超过3亿台开关周期的运行寿命，在-40℃至+ 85℃的宽温度范围内没有降低性能。95 dBm线性度能够显着降低失真，这是要求诸如5G梁转向天线之类的RF应用的关键因素。

The MM5140 switch features a custom-designed, built-in high-voltage charge pump/driver circuit integrated into a miniature 5.2 mm x 4.2 mm LGA package, eliminating the need for external components, simplifying customer layouts and reducing BOM cost. The integrated charge pump circuit offers both flexible SPI and GPIO digital interfaces, enabling easy control from any host processor or test system.

The switch’s highly integrated design reduces cost and design complexity and simplifies the development of numerous RF front-end systems including transmitters and receivers, RF filters, and beamforming antennas used in advanced radio architectures and radar systems. The high channel density and low losses also make the MM5140 ideal for ultra-compact switch matrices and multiplexers used for RF test and measurement applications.
