CC1190: CC1190 - output impedance over frequency

Dan Ringger

Part Number: CC1190

I am working on an application that involves the CC1190 (PA) from TI. I would like to request your assistance if possible; in order to match the (PA) to an antenna, I was wondering if TI might have the output impedance of the (PA) over frequency or the recommended match of the (PA) over frequency. Thank you

Hi Dan,

Looking at the schematics in section A1 here: www.ti.com/.../ , we recommend replicating the match from the CC1190 to L24 as closely as possibly, including layout. The following pi-network, C218, R12 and C23, is used for matching the antenna impedance to 50 ohm.

Regards,
Fredrik

Hi Fredrik - Thank you for your response. The link you provided for section A1 is broken...can you share the specific document name so I can locate it on TI.com?
