ideal balun

Does anyone know how to use ideal balun in cadence? I need to drive differential LNA. Can I give input to Diff LNA without balun? thanks in advance.

Yes , there is a ideal_balun in analogLib and balun(verilog) in rfLib...

A balun is a symmetrical circuit and performs only differential-to-single ended conversion. Input and output impedances may be different than 50 Ohm.

if you use specture
xfmr
you will find in analogLib
you can use it to form an balun i think
