Abstract
A medical device communication system transmitter may include a resonator coupled to a local oscillator for stabilizing an operating frequency of the local oscillator. A control device of the transmitter receives an open-loop control signal, and the local oscillator and the control device are configured to generate a direct modulated radio frequency transmission signal in response to the open-loop control signal.
