    Abstract: Devices and methods determining phase offsets are disclosed. A first test signal is transmitted from a first RF circuit part to a second RF circuit part, where a phase difference between the first test signal and a reference signal (ref) is measured. A second test signal is transmitted from the second RF circuit part to the first RF circuit part, where a second phase difference between the second test signal and the reference signal (ref) is measured. Phase offsets of a connection between the first and second circuit parts or of a line supplying the reference signal are determined based on the first and second phase differences.

    Abstract: Techniques (implemented in circuit arrangements, methods, computer instructions) are disclosed which permit digital pre-distortion for amplifiers. A common signal source provides a common analog signal from a digital input signal; a plurality of amplifiers amplifies a split signal which is a split version of the common analog signal; a built-in test circuit is configured to provide distortion information associated to distortion affecting the amplifier. The common signal source implements a signal conditioner to perform, in a signal path of the digital input signal, a feed-forward pre-distortion of the digital input signal according to a pre-distortion relationship mapping the digital input signal onto a pre-distorted version. The signal conditioner is configured to adjust the pre-distortion relationship in dependence on the distortion information.
