Abstract: According to an embodiment, a device includes an interface configured to receive a first clock signal. A delay circuit is configured to add variable delays to the first clock signal based on a delay control signal to generate a second clock signal with variable delays. A delay control signal is generated by a controller clocked by the second clock signal. The device further includes a radio frequency path, and the device is configured to control the radio frequency path based on the second clock signal.
