  1. ECE 431 Radio Enclosure Design Project Vladimir Goncharoff

  2. Introduction ECE 431 – Analog Communication Circuits (RF Circuit Design)

  3. Laboratory Project: AM Broadcast Band Receiver (500-1700 KHz) Manual and Digital Tuning Every student builds a radio Prototyping-style construction method

  4. Manhattan-style construction:

  5. Design Problem: There is too little space on the existing copper-clad board to allow for expansion and experimentation

  6. Solution Approach: Redesign the radio enclosure to accommodate a larger circuit board (or boards)

  7. Research Identify needs and wants Survey prospective customers Study existing designs Brainstorm design alternatives

  8. Desired Enclosure Features Increased circuit board area than the existing design Easy to manufacture Low materials cost Helps with constructing and testing the radio circuits Low EMI with the outside world Low EMI between different sections of the radio Aesthetically pleasing appearance Sturdy

  9. Existing Radio Enclosure Design

  10. Possible Improved Enclosure DesignsCross-Section Sketches

  11. Design Alternative #1 6” x 12” single-sided board

  12. Design Alternative #2 5” x 6” double-sided board

  13. Design Alternative #3 Two 5” x 6” single-sided boards

  14. Design Alternative #4 Two 5” x 6” single-sided boards

  15. Design Decision Matrix

  16. Design Alternative #1 is “best”

  17. 3-D Models of the Final Design
