CC2500: Alternative BALUN to Johanson 2450BM15B0003E

Hi

The Johanson BALUN (2450BM15B0003E) is directly matched to the CC2500.

There is currently no stock of this part at Digikey or Mouser. Mouser will have stock in August. I need production sooner than that.

1. Do, for example Murata or TDK, make similarly marched parts (for the CC2500)?

2. The CC2500 differential load impedance is stated as 80+J74. There are plenty of parts that are a physical match but their impedance is stated as 50/50 or 50/100 or 50/200 ohm

Here is a list from Digikey

Are any of these suitable?

Or am I stuck with just the one part?

Thanks

Andre
