ABSTRACT
—D-band communications are envisioned for the next frequency step forward to support the future back-haul networks. Beyond technology developments that aim to tackle circuits and systems, testing approaches also need to support the frequency upgrade of systems. This paper presents the photonics approach to generate modulated signals in the range 110−170 GHz. Typical performances that can be reached using standard lasers are discussed, as well as the measurement of error vector magnitude induced penalty in relation to the power-compression curve of a D-band amplifier under test.
