The AMIS-53000 is a highly flexible single-chip CMOS transceiver designed for use in low- to moderate-data-rate (sub-1GHz), low-power, narrow-band, FSK/GFSK/OOK, multiple-channel, wireless applications within the medical market. It can be utilised in implant-communication services, cardiac-rhythm management, neurological-stimulation management, remote patient monitoring, continuous blood glucose and wireless medical telemetry systems. By delivering extensive frequency agility, the device allows designers to use the same part across a range of applications and geographies, while reducing the bill of materials.
