Characterization of a 1 mm (DC to 110 GHz) Calibration Kit for VNA

TDR and VNA Techniques for PCB Characterization

A uniform transmission line is described electrically by a characteristic impedance and a time delay. From the length of the line and the time delay, the effective dielectric constant can be extracted. Two instruments are commonly used to measure these properties, a time domain reflectometer (TDR) and a vector network analyzer (VNA). In this paper, these techniques are reviewed. We show that an...

Calibrating photoreceiver response to 110 GHz

We have measured the magnitude and phase responses of a photoreceiver to 110 GHz using a calibrated electro-optic sampling system. The frequency range of the calibration is limited only by our 1 mm coaxial connectors. In this paper, we present a method for accurately characterizing the response of a commercially available photoreceiver to 110 GHz, nearly three times the bit rate of 40 Gb/s opto...

Experimental characterization of a hybrid fiber-wireless transmission link in the 75 to 110 GHz band

Characterization of Coplanar Waveguides on AlGaN/GaN HEMT on Silicon Buffer Layers up to 110 GHz

*Corresponding author email: [email protected] Abstract In the present work we report the characterization of coplanar waveguides (CPWs) implemented on AlGaN/GaN HEMT layers deposited on high-resistivity silicon (HR-Si) substrates, up to frequencies as high as 110 GHz. The topic is of interest because it is fairly widely held in the community that substrate losses could hinder the application of...

Channel Sounding System for MM-Wave Bands and Characterization of Indoor Propagation at 28 GHz

The aim of this work is to present a vector network analyzer based channel sounding system capable of performing measurements in the range from 2 to 50 GHz. Further, this paper describes an indoor measurement campaign performed at 26–30 GHz. The sounding system is capable of receiving two channels and transmitting one. Using this feature a channel measurement has been performed using both a dir...
