Additional Details
The MICRF113YM6 operates with a supply voltage range of 3.0V to 5.5V. The integrated AGC ensures stable performance over a wide range of input signal strengths. The wake-up timer reduces power consumption by periodically enabling the receiver to check for incoming signals. The device is designed for low-data-rate applications, typically up to 20 kbps. The SOT23-6 package allows for compact PCB designs. An external antenna is required for optimal performance. It is widely used in security systems, home automation, and industrial control applications where reliable and low-power wireless communication is critical. Its high sensitivity makes it suitable for applications requiring long communication range.
