Tetley FEM

The Frequency Extender Module (FEM) is a powerful autonomous add-on module that enhances the existing capabilities of our 5G-capable Tetley Scanners. It allows Tetley Scanner to survey 5G FR2 frequencies in mmWave range between 26.5GHz – 43.5GHz for real-time and post-processing analysis.

The FEM seamlessly integrates with the Tetley Scanner with minimal user interaction required. It digitally down-converts 5G New Radio FR2 frequencies and displays them on the existing user interface along with all 5G overhead messages following the 3GPP specification. Once the FEM is configured with the Tetley Scanner, there is no need to swap RF cables to support sub 6 GHz and FR2 survey.

The FEM supports a bypass mode which allows it to route 3 to 6 GHz signals directly to the Tetley Scanner. This bypass is achieved by connecting both the Tetley Scanner’s High band antenna (3 to 6 GHz) and the FEM’s FR2 antenna to the FEM unit. Controlled by Tetley Scanner via USB interface. The FEM kit is compact and portable, making it ideal for drive-testing 5G mmWave operating between 26.5 GHz – 43.5 GHz.
