AM modulated power supply
A power supply with a modulated voltage output is required for modulation of AM transmitters final stages, Gunn diodes in gigahertz domain. This AM power supply delivers 6V to 8V in repose ( adjustable with P1 ) and between 3V and 10V when it is modulated. Frequency domain is from 200Hz to 30KHz.
Without any load the modulator current consumption is 5mA. If T2 is cooled enough the power supply can deliver 800mA at 6V output voltage.
