Brine for smoking salmon

Hi everybody. I smoked a salmon fillet yesterday in a electric smoker and used a brine that I googled. It called for salt plus soy sauce and to my tastes it was really overly salty. It had a good smokey flavor from using alderwood chips but it was still overly salty. Brought some to work and everyone seemed to like it (Or they were being polite). Any body have a brine recipe they would like to share? Thanks.
