how can i simulate a balanced-unbalanced (BALUN) transformer in Pspice?
 

pspice balun

Hi,

You can use transformers or transmission lines. Look how to use it in the following links :

Replace * by t

Re: BALUN in Pspice

Hi,

You can use a 'K' device. Put this 'K' device on the schematic and its properties Set L1 to Lp1, set L2 to Lp2 and set L3 to Ls. Edit also Lp1, Lp2 and Ls properties and set their respetive values (ex : Lp1 = 10µH, Lp2 = 50µH, Ls = 5µH).

You can also adjust the coupling parameter's value. Max value is 1.

Look here for a graphical example :
