Two New Six-Port Reflectometers Covering Very Large Bandwidths
نویسندگان
چکیده
This paper presents two new structures for six-port reflectometers with very large operating bandwidths of more than three decades, using a combination of lumped reflectors and transmission lines. Circuits working over a range of 2 MHz to 1300 MHz and 2 MHz to 2200 MHz have been built using inexpensive passive surface mount elements and Schottky detector diodes. Comparing results obtained from the new proposed structures with those obtained from a commercial network analyzer showed a worst case absolute value of 0.020 for the complex difference between the measured reflection coefficients. A convenient calibration procedure, for the entire band, is proposed using three standards and four approximately known loads.

متن کاملA new method for automatic calibration of 5-port reflectometers
The five-port reflectometer has been recently applied to demodulators and radars, offering an alternative to classic In-Phase/In-Quadrature (I/Q) discriminators. In these applications, calibration of the reflectometer is an important task. Most of the methods developed are suitable for the instrumentation and measurement field and present a high degree of complexity. We propose in this paper a ...

The design of compact wideband microwave reflectometers for the purpose of inclusion in a breast cancer detection system is presented. In this system, a wideband frequency source is used to synthesize a narrow pulse via the step-frequency synthesis method. The reflectometer undertakes measurements in the frequency domain and the collected data is transformed to the time/space domain using IFFT....
