Help crossing a Minicircuits RF transformer to Coilccraft.

I'm building a circuit that specifies a Minicircuits T1-1T-X65 Rf 
transformer,

Because of price and ease of purchase I wonder if I can sub this Coilcraft part,

I'm confused by the Minicircuits 50 ohm spec, totally missing on the Coilcraft page. Coilcraft gives Inductance, Minicircuits doesn't. Is it just assumed these are designed for 50 ohm systems? Thanks Mikek

The plots are all made in a 50-ohm system. Cheers Phil Hobbs -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510 http://electrooptical.net https://hobbs-eo.com

Thanks Phil, I put some on a Mouser order. I splurged and got the lower frequency, flatter response SWB1010-PCL for an additional $0.27 ea. Mikek
