DESIGN PROJECT REQUIREMENTS
EC En 541 Active and Passive Filters
Winter Semester 2018
Instructor: Dr. David Long
One of the key products in industry is a written design report. In order to give you some practical experience, you will design, build, and test a filter and prepare a report on your results. The final report should be 5-10 pages in length and have at least 3 references. The report should describe the design and the measured filter performance. The rubric used for grading the reports is shown below. Include a photo of your filter as well as S11 and S12 plots.
(1) A narrow band-reject filter for a radio transmitter (or reciever) that rejects the frequency range associated with L-band GPS signals. The filter should have minimal loss for 300-2000 MHz.
(2) A narrow bandpass filter centered at 905 MHz with a rejection of -40 dB at GPS frequencies. The filter should pass frequencies of 900-920 MHz with minimal loss.
(3) A low pass filter with a 3-dB corner frequency of 450 MHz or less that passes 405-420 MHz with minimial loss. The filter rejection for frequencies greater than 1 GHz must be 60 dB or more.
The design report is due 5 April 2018.
