SUB-GHz

Description

The Industrial, Scientific and Medical (ISM) unlicensed Sub-GHz radio frequency bands are used for many short-range, low data-rate, and low-power wireless applications. Microchip provides stand alone transceivers and receiver products along with our family of rfPIC transmitter with embedded PIC® microcontroller.

These radio solutions are ideal for AMR metering, consumer electronics, home, business, industrial automation, automotive, toys and medical applications.

Hardware Solutions

Microchip provides Sub-GHz RF solutions to our customers which complement our PIC family of microcontrollers. These products provide a flexible, cost-effective platform for customers to create the optimum wireless products and solutions for their given application.
