LP-CC2652RSIP: CC2652RSIP ANTENNA

Hi Kumaravel,

1. The CC2651RSIP does not use an internal antenna. See the image below:

2. No internal antenna to disable. Internal antenna is only supported in MODA or SIPA package.

3. Populate the matching circuit shown in the schematic.

4. Internal antenna is only supported in the MODA or SIPA packaging, but if you need it I will search our repository for it.

5. Have configuring the board to conducted, U.FL connector and using an RF cable.

I am using CC2652RSIP which has internal antenna right?

how it works to send data via RF drivers  when internal antenna is not present 

my question is CC2652RSIP I am not connected with any external antenna and there is no internal antenna also but when I send data from the smart Rf or CCS my packet data is been transfered . 

How it internally works 

What I understand is data in thr RF core is been transmitted due to lickage of radiation via external antenna  Is is right?

TX transmission with the internal antenna should not be possible with the RSIP package as none exist. Are you sure you don't have the RSIPA?

I have noticed that their is an integrated pcb antenna within the launchpad

I am also attaching the inverted antenna datasheet for your reference

My query is how to connect external CC-Antenna-DK2 kit

Use the RF cable similar to the image below and connect the SMA.

can you please help me by giving the full setup as an example of connecting the external antenna
