About MC1320 Daughter Board Schematics

Hello,

 

I want to ask a question about the Freescale product, MC1320x RF daughter card.

There are two different designs in your database for the RF daughter card schematics.

They differ on the RF end portion. While one has two capacitors before the inverted-F and SMA antenna whereas the other one has two resistors instead. On the other hand, the latter places the SMA after the bandpass filter.

 

I wanted to learn if those make changes in terms of transmission power or frequency. I add the links below:

Thanks,

Yavuz
