  1. Midway presentation Summer 2010 Quad Carrier Wave Source High Speed Digital Systems Lab Electrical Engineering Technion Instructor:YossiHipsh Student: Boaz Hanina

  2. Table Of Contents • System Block Diagram • VCO As A Multiple Signal Oscillator • 4 to 1 Power Combiner • System Layout • System Practical Operation – room 319 • “To do” List • Gantt

  3. System block diagram Power Combiner Mini Circuits ZN4PD1-50+ EVB(Evaluation Board) F1 F2 VCO2 ADF-4350 VCO1 ADF-4350 OUT EVB(Evaluation Board) f f f f f2 f3 f4 f1 f f1 f2 f3 f4 USB USB F3 F4

  4. VCO As A Multiple Signal Oscillator • The VCO is able to produce 1 - 4.4 GHz signal • Signal A – VCO output divided by 1/2/4/8/16 • Signal B – the VCO output VCO signal VCO signal after division

  5. VCO As A Multiple Signal Oscillator • 2 VCO’s produces 4 signals - Signal A Signal B Signal C Signal D VCO1 VCO2

  6. High Speed Power Combiner • Bandwidth - 0.5 to 5 GHz • 4 to 1 combiner • High isolation – 23db typical value • Insertion loss -

  7. System Layout Power in USB-1 USB-2 System Output

  8. System practical operation 4 output frequencies – 1.6, 2, 3.2 and 4GHz 1.6GHz First harmony 2GHz First harmony 1.6GHz Second harmony 2GHz Second harmony 3.2GHz First harmony 4GHz First harmony

  9. System practical operation VCO2 – 2 and 4GHz VCO1 – 1.6 and 3.2GHz

  10. “To do” list • System mechanical assembly • VCO Signal spectrum analysis using spectrum analyzer. • System output signal spectrum analysis using spectrum analyzer. • User manual.

  11. VCO Signal spectrum analysis • The VCO is the oscillator of the system. • Since the scope bandwidth is Limited, We can’t get the “real” signal spectrum. • Target - determine the quality of the square wave using spectrum analyzer.

  12. System Signal spectrum analysis • The scope is not enough to determine the signal quality. • Characterize the system output signal using spectrum analyzer.

  13. Gantt
