Other Parts Discussed in Thread: CC2538, CC2592

Hi TI team

my HW Board(CC2538+2592) control end device(CC2652) just only 20m.

The antenna is onboard antenna(50 Ohm matching)，I think have a 2592 chip,this Communication distance Shouldn't be 20 meters.

Have any suggestion?Thanks!

Hi, TER

OK, in my side,I had found the CC2592 module hardware inductance(L17) was penetrated,

and now had improve the commumication distance from 20m to 35m(most).

Spectrum Analyzer had test the Hardware had 19DBM Tx_Power.

It is not normal because it is CC2538 had the CC2592 module.

Could you give me more advise?Thanks!

Does that mean you have 19 dBm conducted output power?

What about the conducted sensitivity measurements and antennas which the app note ask about?

It's not possible to pinpoint what could be wrong without basically any information about the design.
