Abstract
Ultra wideband (UWB) radio offers low power consumption, low power spectral density, high immunity against interference and other benefits, not only for consumer electronics, but also for medical devices. A cochlear implant (CI) is an electronic hearing apparatus, requiring a wireless link through human tissue. In this paper we propose an UWB link for a data rate of 1.2 Mbps and a propagation distance up to 500 mm. Transmitters with step recovery diode and transistor pulse generators are proposed. Two types of antennas and their filter characteristics in the UWB spectrum will be discussed. An ultra low power back tunnel diode receiver prototype is described and compared with conventional detector receivers.
