Murata offers a new addition to its Type 1RM family of ultra-small Medical Implant Communication System (MICS) band radio modules. The module uses the 402-405MHz frequency band. It supports a 128kbps data rate and can incorporate a communication range of up to 2m.

The new module is intended for use in body-worn and implantable monitoring/diagnostic devices, with the capability to address even the most data-intensive of operational demands. Typical applications include insulin, drug, and baclofen pumps, as well as arrhythmia and bladder monitors.

Supplied in a remarkably compact form factor, measuring just 8.6mm x 5.6mm x 1.7mm, this module is one of the smallest and most highly integrated solutions on the market. It leverages the company's proprietary wireless technology, which combines all the key constituent active and passive components into a singular miniaturised package. As well as its elevated performance, the resultant module provides a very low power budget with a sleep state current consumption of only 0.2µA.

“This latest addition to our Type 1RM family underlines the primary impetus behind Murata’s philosophy – to help create a better society by developing innovative, class-leading solutions,” said Rui Ramalho, product manager for Connectivity Modules at Murata. “Through our numerous MICS variants and the unique bundling technology employed by them, Murata is helping to improve the lives of patients with serious health conditions.”
