Abstract :
A new type of spectrum analyzer (SWIFTS) based on RF interferometry using a low-cost microstrip technology is presented. The acronym SWIFTS was chosen for stationary waves integrated Fourier transform spectrometer. The SWIFTS enables both broadband and fast measurements. It consists of a waveguide ended by a short circuit. Power detectors are periodically spaced along the standing wave to sample the signal. The spectrum is obtained with a Fourier transform calculation. A 0.3-5 GHz prototype was built to validate the concept. Measurements on a real cellular phone are presented and discussed.
