+# 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
+-
