Abstract
Test signal circuit for testing a radio frequency receiver circuit, including: a test signal generator configured to generate a baseband test signal, a modulator configured to modulate a local oscillator signal with the baseband test signal to generate a test signal, a first transmission element coupled between the modulator and an input of an impedance transforming element, a second transmission element coupled to an output of the impedance transforming element, the impedance transforming element configured to lower a first impedance level of the first transmission element to a second impedance level of a second transmission element, a voltage level detector coupled to the first transmission element, the voltage level detector being configured to detect a voltage level of the test signal. The disclosure further relates to a semiconductor chip including the test signal circuit and a system including the test signal circuit and a control circuit.
