The ZL70103 is an ultra-low-power RF transceiver chip from Microsemi that supports a very high data rate RF link for use in implanted medical devices, base stations, and other implantable communication applications. This half-duplex communications link is designed to operate in the 402-405 MHz MICS band, otherwise known as the Medical Implantable Communications Service band, which is a subset of the designated MedRadio frequency band.
