Abstract: Techniques for reducing interference among transceivers are disclosed. A transistor generates a radio frequency transmit signal in response to a generated pulse. The pulse is generated when transitions are detected in a clock signal. The clock signal is produced by an oscillator block which includes a ceramic resonator configured as a clock source. When interference is detected, the pulse applied to the transistor is varied. The frequency of the transmit signal is optionally modulated by varying the temperature of a resonator element. To vary this temperature, the current flowing through one or more resistive elements positioned in proximity of the resonator element is varied according to a control signal. As the level of this current flow varies, the amount of heat emitted by the resistive elements varies, thereby changing the temperature of the resonator element which has a relatively high temperature sensitivity.
