Our sub-GHz portfolio delivers the industry’s largest link budget. We achieve these results by offloading system-level functions from the MCU to reduce power and computation burden.
Our sub-GHz product portfolio supports OOK, ASK, FSK, O-QPSK and ORDM modulations with data rates from 1 kbps to 2,400 kbps.
We support all ISM frequency bands and offer the only commercially available device that supports 2.4 GHz and sub-GHz bands simultaneously.
Low-IF receivers provide high sensitivity, high blocking and low intermodulation, eliminating the need for bulky blocking Surface Wave Acoustic (SAW) filters in remote control units.
We provide low current consumption in all three modes—operation, idle and sleep—to give you long battery life (in some cases years).
Our sub-GHz transceivers provide an adjustable power range starting at −17 dBm and going up to +14.5 dBm.
Consuming about 75% less power than Wi-Fi, sub-GHz is the optimal wireless technology for low-cost, robust and low-power sensor networks such as metering, smart building and smart city applications.
RF remotes provide reliable wireless control that is critical for a wide range of industries, from home automation to industrial systems. This demo includes a remote-controlled garage door opener that communicates with a Bluetooth Low Energy or sub-GHz base station and implements KeeLoq® technology crypto key generation for added security.
MPLAB® Harmony is a modular framework that provides interoperable firmware libraries for application development on 32-bit microcontrollers and microprocessors.
Microchip Studio is an Integrated Development Environment (IDE) for developing and debugging AVR® and SAM microcontroller applications. It merges all of the great features and functionality of Atmel Studio into Microchip’s well-supported portfolio of development tools to give you a seamless and easy-to-use environment for writing, building and debugging your applications written in C/C++ or assembly code.

Sub-GHz, sometimes called sub-1-GHz, refers to the radio frequencies that fall below 1 GHz on the electromagnetic spectrum. These frequencies are significant in the wireless industry due to their unique characteristics and advantages.
Firstly, sub-GHz signals possess excellent broadcast capabilities, allowing them to travel over long distances and penetrate obstacles such as walls and buildings more effectively than higher frequencies. This characteristic makes sub-GHz technology well-suited for applications that require wide coverage, such as smart cities, industrial automation, agriculture and utilities.
Sub-GHz frequencies also offer improved robustness and reliability in challenging environments. They are less susceptible to interference from other wireless devices that operate at higher frequencies, providing more stable communication. This makes sub-GHz technology optimal for applications that demand high reliability and security, such as wireless sensor networks, remote monitoring and control systems.
Lastly, sub-GHz solutions often have lower power consumption compared to higher-frequency alternatives, resulting in extended battery life for wireless devices. This energy efficiency is particularly valuable in applications where frequent battery replacement or recharging is impractical or costly.
In summary, sub-GHz frequencies play a crucial role in the wireless industry by enabling reliable, long-range communication with excellent penetration capabilities and low power consumption.
The 315 MHz and 433 MHz bands are used globally, but the other bands are only supported in specific regions. Here are some of the most popular sub-GHz bands and frequencies used around the world:
