AWR1243: AWR1243 impedance and power info on pins B15 and B1

Viktorija Cecil

Part Number: AWR1243

Team,

My customer is working on AWR1243 design, and need help answering some questions:

We will be using pins B15 AWR1243 design (FM_CW_CLKOUT) and B1(FM_CW_SYNCIN1).  We have a following questions.

1. What is the input power range (minimum and maximum)  required for B1?

2. What is the nominal power output of B15?

3. what are the input impedance of B15 and B1? 

4) or/and provide a reference design of impedance match to the external transmission lines.

Thanks

Viktorija

    Hello Viktorija,
    I assume you are attempting to use cascade configuration with the AWR1243.
    The CW_SYNCIN pins expect a 20Ghz signal at about 0dBm level. The CW_CLKOUT pin outputs the 20Ghz clock at ~6dbm level.
    The impedance is 50ohms and needs to be continued on the PCB as well.

    regards,
    Vivek
