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
