Abstract:
A signal scaling device (D), for a transmission path of a wireless communication equipment, comprises a processing means (PM) adapted to receive a phase and/or amplitude modulated signal (I/Q) to transmit, and arranged to multiply said phase and/or amplitude modulated signal with a chosen complex gain in order to output said phase and/or amplitude modulated signal with a chosen scaled amplitude and a chosen phase offset.
