The first week meeting

[x] ---30/01/2020 by Yimian Liu
[x] Participaants: Boyao Yang, Weizhou Wen, Yimian Liu, Yidi Song
[x] Location: EE 5 floor AA office

Outline

  • Figure out the key params of FDC
  • Think how to measure these params
  • There might be a week to wait for the SMT
  • In the waiting time, figure out measure/test procedure and plan
  • Always think about the Report
  • Use blog to provide evidence of proof
  • Its better to conduct the proj document-oriented with a check list

Technical Suggestions

  • Do not need a bandpass filter at input
  • Do not need a amplifer at input and output
  • May need a bandpass near output
  • Think how to design the output impandance to be 50ohms
  • The output bandpass may use butterworth
  • The gain can be not considered
  • The input can be designed to be any range between 300M-3GHz, 1850-1910MHz is ok

Second AA Meeting

[x] ---06/02/2020 by Yidi Song, Yimian Liu
[x] Participaants: Boyao Yang, Weizhou Wen, Yimian Liu, Yidi Song
[x] Location: EE 5 floor AA office

Ques

  • LT5512 spice models
  • the size and layers of PCB
  • Design details about IF LPF
  • BNC adapter

Techninal Suggestions

  • Use spice to simulate
  • Find some similar IC simulation models
  • Set up the IC by what we want to test
  • Remove all unnecessary Filter and only leave mixer
  • Altium Designer is recommanded to use
  • Contact lab members to find out the port of spectrum analyzer
  • Buy SMA-BNC adapter if necessary
  • Components list ASAP, do not suggest to buy by ourselves

Third AA Meeting

[x] ---13/02/2020 by Yimian Liu
[x] Participaants: Boyao Yang, Weizhou Wen, Yimian Liu, Yidi Song
[x] Location: EE 5 floor AA office

Ques

  • Ques about the usage of resistance in demo
  • Ques about the impedance matching
  • Ques about PCB differentical line design

Techninal Suggestions

  • Resistance is used to perfect the circuit
  • impedance match sometimes do not really necessary in this case
  • just make sure that there are input and output

Fourth AA Meeting

[x] ---20/02/2020 by Yimian Liu
[x] Participaants: Boyao Yang, Weizhou Wen, Yimian Liu, Yidi Song
[x] Location: EE 5 floor AA office

Ques

  • PCB design problems
  • convert gergle to brp
  • how to submit PCB design

Techninal Suggestions

  • Place through hole alone the high frequency line
  • Use Laying copper to ground most place
  • Check the minimum width of wire
