Millimeter-Wave Network Analysis using Nonlinear Transmission Lines

چکیده
We report systems for network measurements at millimeter-wave frequencies. Active probes are used for on-wafer measurements to approximately 150 GHz. The active probes incorporate monolithic GaAs mm-wave network analysis circuits (comprising a nonlinear transmission line stimulus signal generator and a directional sampling circuit) and lowloss, rugged quartz coplanar-waveguide probe tips. Wideband transmitter and receiver integrated circuits, incorporating nonlinear transmission lines and sampling circuits interfaced to frequency-independent antennas, are used for free-space transmission measurements to approximately 250 GHz.

Millimeter-Wave On-Wafer Waveform and Network Measurements Using Active Probes
Absiract-We have fabricated active probes for on-wafer waveform and network measurements. The probes incorporate GaAs nonlinear transmission line (NLTL) based network analyzer (NWA) integrated circuits and low-loss quartz coplanarwaveguide probe tips. The active probes show step response falltimes of 2.7 ps when excited by a 0.7-ps falltime input. Using these active probes, we demonstrate both ...

متن کاملBroadband Millimeter-Wave GaAs Transmitters and Receivers Using Planar Bow-Tie Antennas
We report broadband monolithic transmitters and receivers ICs for mm-wave electromagnetic measurements. The ICs use non-linear transmission lines (NLTL) and sampling circuits as picosecond pulse generators and detectors. The pulses are radiated and received by planar monolithic bow-tie antennas, collimated with silicon substrate lenses and off-axis parabolic reflectors. Through Fourier transfor...
متن کاملSpice Compatible Model for Multiple Coupled Nonuniform Transmission Lines Application in Transient Analysis of VLSI Circuits
An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...

In this paper, we designed and analysis the aperture-coupled microstrip array antennas for the short range radar (SRR) system. These antennas can be designed with transmission lines and matching circuits in the same substrate LTCC. We achieved the proper impedance matching throughout the corporate feeding array configurations provides the lossless T-junction. In order to more exactly match in t...
