While climbing thru FL250 we began to smell something that resembled an electrical burning type scent; then noticed some faint smoke in the flight deck and cabin area.  We immediately accomplished our memory Items for Smoke/Fire/Fumes; which included putting on our oxygen masks; and followed up with the QRH.  At this point we leveled off our climb and attempted to communicate with ATC; and changed our transponder code to 7700.  An Emergency Descent was initiated; at which point we heard ATC trying to call us.  We realized after several attempts to transmit; that ATC was not able to hear us.  We then switched to our Secondary Radio and were able to establish communications with ATC.  As we were in close proximity and the crew was familiar with the airport; we chose to divert to ZZZ.  We had no other indications of smoke or fumes after the initial scent/smoke.  We accomplished a landing on runway XX at ZZZ.  With no smoke or signs of smoke in the aircraft and Crash/Fire/Rescue reporting no signs outside the aircraft; we taxied to the FBO ramp and shutdown/inspected the aircraft.   This event was in an Embraer Phenom 300 (EMB-505).
