Abstract
Devices and methods related to devices capable to perform digital output power measurement besides attenuation control are provided. A device includes a digital signal processing unit, a transmitter and a feedback receiver. The digital signal processing unit is configured to control attenuation along a transmission path and a feedback path based on a comparison of a power of a digital input signal with a raw power of a corresponding digital feedback signal, and to calculate an output power value of an analog RF signal to be broadcasted, using the raw power of the digital feedback signal and one or more feedback gain factors related to gain in the feedback receiver.
