Ummm ... hate to say it bro ... but *ALL* RF is ANALOG ... even "digital" ... now some amplifiers may be "Class C" or "Class D" but when that stuff gets put into a coil or an antenna, rest assured that it's sinusoidal in the minimum degree. Sorry bro - I *did* this stuff for a living until the very LAST manufacturer got on a slow boat to Bombay. Even your most EXOTIC "digicomms" is ANALOG.

Hell ... "Digital TV" was invented in 1926 ... take a look at the horizontal sync pulses (with or without equalizers in the VBI) of ANY TV system from them until "intercarrier" ... they claimed THAT was digital too. :)

An RF amplifier designed to be matched at 25, 50, 75, 300 or other ohmage is going to SMOKE when it sees two ohms at the load. :)
