Part Number: AWR2243
Other Parts Discussed in Thread: AWR1642, AWR1243,

Hello support team.

For production, customer is changing AWR device from AWR1243P to AWR2243P for evaluation.
Then, customer needs to know about the impedance change of each TX/RX ports on AWR1243P and AWR2243P.
Please share the impedance informaton for both AWR1243P and AWR2243P.

Hello Koro San,

There is no change in device impedance between 1243 and 2243P devices.

Hello Vivek-san.

Thanks a lot for keeping support.

I checked your mentioned link.

It is for AWR1642.

I would like to know if AWR1243 and AWR1642 the same in S parameter.

Also customer wants both AWR2243 and AWR1243 value because they need to compare their values of AWR2243 and AWR1243 for moving device.

Hello Koro San,

The S parameters are the same for 1642 and 1243 device. For 2243 also the impedance is similar.
