On-Wafer Vector Network Analyzer Calibration and Measurements
The representative VNA block diagram (see Figure 1) shows the key elements of the analyzer. The RF source at the top provides the device-under-test (DUT) stimulus. A forward/reverse switch directs the RF energy to either DUT port. The test set uses directional couplers or bridges to pick off the forward and reverse waves traveling to and from each port, and down-converts these signals to four I...
متن کاملAn Optimal Vector-Network-Analyzer Calibration Algorithm
We present an iterative algorithm for calibrating vector network analyzers based on orthogonal distance regression. The algorithm features a robust, yet efficient, search algorithm, an error analysis that includes both random and systematic errors, a full covariance matrix relating calibration and measurement errors, 95% coverage factors, and an easy-to-use user interface that supports a wide v...
متن کاملLow-cost Vector Network Analyzer for Biomedical Applications
A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...
متن کاملDetermination of Permeability from Impedance Measurement Using Vector Network Analyzer
This study treats the optimised one-port (reflection coefficient) and two-port (shunt-through/series-through) measurement methods for complex permeability determination of solid soft magnetic materials using a vector network analyzer (VNA) at frequencies from 9 kHz to 6.5 GHz. The principle of measurement methods, the relationships of measured phasor voltage ratio (Sparameter) to complex impeda...
متن کاملVector-Network-Analyzer Calibrations
We develop an uncertainty analysis that captures the dominant sources of measurement error in state-of-the-art WM-380 (WR 1.5) rectangular-waveguide vector-network-analyzer measurements over the frequency range 500–750 GHz. We use the analysis to assess thru-reflect-line, thru-short-match, and thru-short-radiating-open calibrations. The comparison shows that thru-short-match and thru-short-radi...
