Abstract:
Active Load or Source Impedance Synthesis Apparatus for experimental characterization of an electronic device under test (E) working in the frequency band from about 500 MHz to about 110 GHz, comprising:an active load loop having at least an amplifier (Am) operatively connected to a directional coupler (Acc) and to a measurement system which can be connected to said device under test (E), the amplifier, directional coupler, and measurement system being arranged so that a signal to be treated in the active load loop from the device under test (E) is sampled by the directional coupler (Acc), is amplified by the amplifier (Am), and is injected back towards the device under test (E) through the coupler (Acc), the most significant losses (LSM) of said measurement system being intermediate the directional coupler and the amplifier.
