A novel vector network analyzer
(IEEE, 1998-12)
A calibration procedure for a perturbation two-port vector network analyzer is presented. It consists of a variable perturbation two-port placed between a device-under-test and a scalar network analyzer. A measured vector ...
Active Resonator
(IEEE, 2001-07)
A new electrical component-active resonator-is designed. The component consists of a common passive resonant circuit whose losses are compensated by an extra active circuit. Experimental verification was done with a TE/sub ...
First results of microwave measurement of broadband radio interference filters
(IEEE, 2004-12)
A vector measurement method for testing multiport interference filters for shielded chambers has been used. Measured data up to 3 GHz are presented. The authors believe that this is the first time such results have been published.
A New Concept of PTP Vector Network Analyzer
(IEEE, 2004-12)
A new concept for vector network analyzers design based on a perturbation two-port (PTP) is presented. The approach uses redundant states of the PTP. The best states of the PTP for a certain place in Smith chart and frequency ...
On radio interference filter measurement
(IEEE, 2003-12)
A new measurement method for on site testing of multiport radio interference filters (RIF) on shielded chamber is designed. The method is based on scalar measurement only and makes possible a pessimistic estimate of the ...
Hidden Problems in Precise Calibration on Microstrip
(IEEE, 2008-12)
A study of calibration problems on microstrip with respect to interaction of electromagnetic fields around SMA to microstrip launcher and microstrip short was carried out in frequency band up to 26 GHz. Omni Spectra SMA ...
