AWR1642: Why the transmit line and the RX antenna are not align in AWR1642BOOST EVM

Part Number: AWR1642

Hi team,

Customer is curious why the transmit line and the RX antenna are not align in AWR1642BOOST EVM reference design sprr261a.zip

Is here any reason why the line is not align? I had attached the details picture of it near RX3 and RX4.

Thanks for your help.

Regards,

Wesley

Hello Wesley,
Those are just tool resolution issues when you connect two Clines. These would be much lower than the etching accuracy in the fab. So those can be ignored.

Hi Vivek,

Thanks for your reply.

So during the layout, is that means we should align transmit line and antenna line as close as possible?
