AWR1843BOOST: RF traces line width and spacing requirement

Anand

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843,

Hi TI,

Whats the requirement of TX and RX RF traces line width and spacing for AWR1843 anntenna layout design?

The Hardwaredesign checklist provided by TI,its mentioned W=7.08mills and S=8mills to achieve 50ohm impededance.But in AWR1843boost layout file RF traces having spacing of 6.87mills only.

Hello Anand,

Please refer to the PCB layout file for the trace thickness and spacing.

Hi Vivek,

Thanks for the information.

Please let me know length match tolerance need to follow b/w RF traces TX1/TX2/TX3 and RX1/RX2/RX3/RX4

Hello Ram,

Typically we target 1mil accuracy based on manufacturability. . But if you can get tighter accuracy that will give you better impedance control.
