MEASUREMENT ARRANGEMENT FOR LOAD PULL MEASUREMENTS COMPRISING A MULTIPLIER BASED ACTIVE TUNER

摘要

Load pull measurement arrangement having an active tuner with a signal generator (2) providing a signal at a first frequency (fO) to a vector modulator (3). The vector modulator (3) has an input for receiving control signals (4), and is arranged to provide an injection signal at the first frequency (fO) based on the control signals (4). The active tuner (1) further comprises a frequency multiplier (5) receiving the injection signal and outputting a multiplied injection signal having a second frequency (NxfO), the second frequency (NxfO) being an integer multiple (N) of the first frequency (fO). Furthermore, a millimeter wave extender (17) is disclosed comprising a frequency multiplier (5) in the signal injection path connected to the device under test (7) during operation.
