RF Module Cures Medical Design Woes

Sept. 16, 2015
A transceiver module is designed for implantable medical applications in the MICS band.

A miniature wireless radio module has been developed specifically for implantable medical devices such as pacemakers, cardiac defibrillators and neurostimulators. The model ZL70323 module measures just 5.5 × 4.5 × 1.5 mm and complements the firm’s ZL70120 module at the other side of the communications link. The module employs a low-power transmitter and receiver operating in the Medical Implantable Communications Service (MICS) band at 402 to 405 MHz, along with a 24-MHz crystal reference oscillator and surface-acoustic-wave (SAW) filters. It includes a “wake-up” receiver at 2.45-GHz which can be used as needed. The module communications health status data and, with its small size, can be implanted with only extremely small incisions required.
