Overview

The Microchip MRF89XAT-I/MQ is a sub-GHz RF transceiver IC designed for low-power wireless applications. It supports FSK and OOK modulation schemes and operates in the 863-960 MHz ISM bands. This device offers a balance of sensitivity and output power for reliable short-range to medium-range wireless communication.

Why Choose This Part

This transceiver offers a strong link budget with -113dBm sensitivity and up to +12.5dBm output power, suitable for diverse operating conditions. Its flexible frequency support across multiple sub-GHz ISM bands enhances its applicability in different regions. The low current consumption in sleep (0.1 uA) and standby (65 uA) modes extends battery life in power-constrained designs.

Applications

Wireless Sensor Networks
Ideal for battery-powered sensor nodes due to its low power consumption in sleep and standby modes, enabling long operational lifetimes.
