Transmitter On A Chip

Radio Schematic

Someone eventually had to do it - and they did. Lithic Systems has announced a comolete AM transmitter on a tiny IC chip. Designated the LP2000, it is capable of 50 MW output on 10 meters when fed by a 12V supply. Operation on 6 meters is also possible with slightly reduced output. The block diagram shows that the chip isn't a simple oscillator modulator as you might expect. Not only does it have two buffer stages between the oscillator and output stage, but it incorporates a power supply...
