Available in PDF, EPUB and Kindle. Book excerpt: This report describes Part II of a program initiated to determine what effects high power UHF/microwave signals have upon solid state components, such as transistors used in RF amplifier stages of high power receivers. The electromagnetic vulnerability (EMV) data needed involves determining the effects of high power 240 MHz RF microsecond single pulse signals upon those transistors. Testing was performed using 2N5179 and 2N918 transistors. A study was made to determine the incident pulse powers required to cause a 50% failure rate. The data suggest that UHF receivers with an RF transistor amplifier front end may be as susceptible to intense electromagnetic radiation (EMR) at UHF frequencies as those with a mixer diode front end.

Book excerpt: The report describes a program that was initiated to determine what effects high power UHF/microwave signals have upon solid state components such as transistors used in RF amplifier stages of UHF/microwave receivers. The effects of CW power at 200 MHz upon the following transistor parameters were monitored: (1) small signal power gain; (2) noise figure; (3) breakdown voltages; (4) leakage currents; (5) Beta (hFE). The one parameter that did degrade significantly when CW UHF power was applied was the dc current gain Beta. A change in Beta from an initial value of 60 to a value of 15 after exposure is a representative case. These changes in Beta occur at incident power levels significantly below that required to cause component failure. The parameter Beta is a good parameter to monitor during CW EMV investigations.

This book was released on 2006-12-18 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio Frequency IDentification (RFID) stores and retrieves data using devices called RFID tags: objects attached to or incorporated into a product, animal or person which communicate with an RFID reader or interrogator. This book proposes a linear two-port model for an N-stage modified-Greinacher full wave rectifier, predicting the overall conversion efficiency at low power levels where the diodes are operating near their threshold voltage. Included is an experimental procedure to measure how impedance modulation in the tag affects the signal at the reader, and a useful tool for choosing the most appropriate impedances.
