A broadband standing wave RF interferometer for fast and low-cost spectral analysis
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.
