Jan03 Drayto6 ECE 5613 RF/Microwave Circuit Design Laboratory Lumped Circuit Element Characterization Lab Using the 2-Port calibration, make the following 1-Port measurements. Perform all modeling in Agilent ADS and LineCalc. 1. Sketch the physical configuration of the resistor soldered to the SMA connector. Measure and plot the return loss response (in dB) of a low frequency resistor mounted to an SMA connector. Answer the following questions in your report. a. What is the dc value? b. How does it vary with frequency? c. Is response consistent with the general circuit model of a resistor? If not, why or why not? 2. Sketch the physical configuration of the reactive element soldered to the SMA connector. Measure and plot the return loss response (in dB) of the discrete capacitor and inductor mounted to the SMA connectors. a.

Unformatted text preview: Draw an equivalent circuit model to describe the response observed on the Smith Chart. {OPTION: To plot the Smith Chart Response, save the data as an *.s2p file. Import the data into ADS 2002 and plot the data as on the Smith Chart. See the TA for assistance.} 3. Measure and plot the RF chip resistor and inductor mounted in a 50ohm transmission line system. a. Draw the equivalent circuit model (using the transmission line). b. Determine the input impedance at 0.5, 1.5, and 2.5 GHz from the measurement as well as the modeled data. 4. Now, measure the RF chip resistor and inductor mounted on a 50-ohm transmission line and include electrical delay to shift the reference plane to the input of the lumped circuit element. Note any observations about the measured response when observed on the Smith Chart....
