  1. ECE 498 Frequency Division Multiplexing On PCB (Printed Circuit Board) Science and Engineering Project Center Department of Electrical and Computer Engineering Seattle University

  2. ECE 498 Frequency Division Multiplexing On PCB (Print Circuit Board) Team Members: Kun-Chin Chien Michael Mitchell Faculty Advisor: Dr. Robert G. Heeren Coord. Advisor: Dr. Al Moser

  3. Our Goal • Incorporation of a FDM circuit onto a PCB to allow students to aim their focus on the study of signal flow

  4. Overview • Project Specifics • FDM Laboratory Winter Quarter 05 • Replacement multiplier IC • New PSpice schematic and PCB layout

  5. Project Steps: • Design of Low Pass & Band Pass Filters • Research a PSpice model for the IC and build the complete schematic into PSpice • Research designs for PCB Footprints • Create the Netlist to be imported into OrCad Layout Plus • Design the PCB layout • Route the PCB layout

  6. FDM LaboratoryOverview

  7. FDM Schematic With IC MC1496

  8. Analog Devices Analog Multiplier AD633JN

  9. FDM SchematicWith IC AD633JN Adder Modulator Band Pass Filter Demodulator Low Pass Filter

  10. Foot Print of the Banana Plug Jack

  11. AMP BNC Connector AMP 222132-1

  12. Foot Print of theBayonet Neill Concelman

  13. Foot Print of theVariable Resistor

  14. Layout of the Circuit(Using OrCad Layout Plus)

  15. Layout of the Circuit (Un-routed)

  16. Layout of the Circuit (6 Layers)

  17. Input 1 Test Point Output 1 +15V Adder Carrier -15V Output 2 Modulator -10V BPF LPF Demodulator 2 Layers Input 2 +10V

  18. Manufactured Price Of the PCB Size of the Board 4.925in(L) X 3.6in(W) Price is dependent on the number of layers, not the number of boards
