# 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
|
|
|
