The International Microwave Symposium in past years has included several events targeted for participation by students. Among these events has been the Student Design Competition. The Student Design Competition presents an opportunity for the students to demonstrate mastery of microwave engineering principles in meeting predetermined design requirements for an interesting set of microwave problems. These Design Competitions, Sponsored by the Microwave Theory and Techniques Society's Technical Coordination Committees in partnership with leading technical companies involved in microwave engineering. These competitions help the sponsoring companies an opportunity to identify strong graduate students and programs for the future development of both the students and the sponsoring companies.
Design Specifications, evaluation criteria and other important information can be found in the rules of 2013 contest (note that rules for 2014 contest are not ready yet):
2013 Balun Design Contest Rules
Wikipedia's definition of a balun:
Explanation of Measurements:
MTT-17 is announcing the fourth student balun design contest that will take place at IEEE IMS 2014.

The competitors are required to design, construct and test a wideband balun at a frequency band starting from a minimum of 1 MHz to as high as possible. There is a need in industry for amplifiers in the high frequency (HF-VHF-UHF) region that cover several octaves of bandwidth. Differential circuits using solid-state devices are ideally suited for these applications, but often require wideband baluns to both transform the differential balanced output to a single-ended unbalanced output, and to also provide impedance transformation. This competition provides the opportunity for students to find interesting solutions to this problem.
