    The FMTx 2.0 implementation is based on the Silicon Laboratories Si4713 low power FM transmitter device. This device has some state of the art features which have been utilised in the Nokia implementation. Apart from having excellent RF transmitter performance and exceptional AF performance the device offers a number of unique features, including the ability to retune the output stage of the device to ensure optimal matching between the Tx antenna and the output stage of the device.

    On RM-235 the _SEN is pulled high by connecting it to VIO. RM-235 uses a loop antenna which is located in the removable C-cover of the device. The loop antenna also acts as the tuning inductor which is required by the Si4713 chip. The location of the antenna in the removable cover means that ESD protection is required to prevent damage to the Si4713 device.
