Abstract
We report on a general technique to characterize the impulse response of a microwave device or network. Very short microwave pulses that approximate an impulse are generated from a mode-locked laser impinging on a fast photodetector. Impulse response measurements have been made with a dynamic range of 40 dB for frequencies up to 50 GHz. A frequency resolution of 50 MHz has been obtained. The accuracy of the measurement is 1 dB in amplitude and 0.1 rad in phase
