The RF interface for the MM61xx includes the option to use either the on-chip amplification for typical low-power, low-cost devices, or an additional external PCB-mount power amplifier (PA) or Front-End Module (FEM) for Ultra-Long-Reach applications. The RF receiver features an ultra-high linearity LNA, making the use of external filters unnecessary in many applications.
Battery-operated applications are supported by a combination of features in the MM61xx. The IEEE 802.11ah standard combined with Morse Micro’s low power design expertise provide for extended sleep times and lower power consumption of battery-operated STA client devices, with longer durations than other prior IEEE 802.11a/b/g/n/ac/ax generations.
Several SKUs (MM611x) add a robust and independent Host Applications Processor (HAP) based on a low power 32b RISC-V core. Morse Micro customers can migrate their operational code to run on the HAP for the most highly-integrated SOC solution to minimize PCB size and costs for Wi-Fi HaLow applications.
