CC2520: CC2520 RF Output Impedance and compatible RF Balun Part number

Prodigy 30 points
Part Number: CC2520
Other Parts Discussed in Thread: CC2530

Tool/software:

Dear TI Technical Team,

I am designing a system with CC2520 ZigBee Transceiver. I am trying to find RF Output impedance information for this part, but I am not able to find it.

I have 3 related Questions -

1. Please let me know the RF Output Impedance RF_P and RF_N (Differential impedance)

2. In one of the notes, its mentioned that Johanson Balun Part No. 2450BM15B0002 is specifically designed for CC2520 for optimum impedance matching. But this part is not available online. Can we use Johanson Part recommended for CC2530 i.e. 2450BM15A0002001E? Could you please recommend any other Balun part number?

3. Is RF Transmitter portion, RF_P and RF_N Output Impedance same for both CC2520 and CC2530?

Thanks and Regards,

Prasad A. Gokhale
