Time to market reduced for implantable medical designers by Microsemi's RF modules

A radio frequency (RF) base station module for implantable devices utilising the Medical Implant Communication Service (MICS) RF band has been launched by Microsemi.

The ZL70123 has been developed for external controllers and monitors of implantable medical devices and when combined with Microsemi’s existing ZL70323 implant module, is said to provide a complete solution for achieving the highest performance in next-generation medical networks (Med-Net).

"RF engineering is a highly specialised discipline and leveraging Microsemi's deep expertise in this area allows our customers to reduce design times and minimise project risk," said Martin McHugh, Microsemi's product line manager for implant modules. "With Microsemi's two-module radio link, companies can now focus research dollars and development efforts on new therapies that enable a better quality of life."

According to Microsemi, its Med-Net radio operates in the 402 MHz to 405 MHz MICS band. Multiple ultra-low power wake-up options are also said to be supported, including a 2.45-GHz, industrial, scientific and medical band wake-up option.

The ZL70323 implant module is said to implement all RF-related functions needed to deploy an implant node in a MICS-band RF telemetry system. It consumes less than 6mA when transmitting or receiving data and 10nA when in its sleep state and the integrated antenna tuning circuit also allows the module to be used with a wide range of implant antennas, Microsemi adds.

The ZL70123 base station module is designed to include all RF-related functions required to deploy external device functions in a MICS-band RF telemetry systems.

"The ZL70123 base station module raises the bar in implant telemetry by offering more flexibility, longer range capability and smaller size than its predecessor, while maintaining backward compatibility with older systems," said Jeff Kuhn, application manager. "Combining the ZL70123 base station module with the ZL70323 implant module, Microsemi's Med-Net radio solution enables deeper implants with strong communication links while preserving battery power."
