Published October 06, 2006
In an effort to better combine the editorial content of our magazine with our newly developed and retooled on-line presence, we have decided to expand Harlan's RF and microwave engineering advice into a monthly feature that appears in Microwave Journal.
Harlan has selected one question from his "Ask Harlan" column to be featured in the October issue. Harlan will be monitoring the responses and will ultimately choose the best answer to the question. Although all of the responses to the featured question will be posted on our web site, we plan to publish the winning answer in the December issue.
You be the expert: Please take a few moments and provide an answer to this month's featured question. Good luck and we look forward to reviewing your answer.
All responses must be submitted by November 9, 2006, to be eligible for the participation of the October question.
Arun Kumar has submitted this month's question:
I am involved in Schotty diode mixer design at microwave frequencies. For accurate design, I want to characterize the diode with the help of the test fixture and network analyzer. As the junction resistance varies with LO power level for characterization of the diode how much LO power should I give? Some literature says that the LO power should be such that the rectified current from the diode is in the order of 1 to 1.5 mA. How then should I measure the rectified current through the diode, which is mounted in the test fixture? Please help.
The winning response will win a free book from Artech House, along with an "I Asked Harlan!" t-shirt. In addition, everyone who submits a legitimate response will be sent an "I Asked Harlan!" t-shirt.
If your response is selected as the winner, you'll receive a free book of your choice from Artech House. Visit the Artech House on-line bookstore at www.artechhouse.com for details on hundreds of professional-level books in microwave engineering and related areas (maximum prize retail value $150).
