# 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 |
|

|
>[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 |
|
