Things oriented LDMOS power amplifier with self-powered function

摘要: The invention provides a things oriented LDMOS power amplifier with self-powered function. comprises tube thermoelectric conversion function, resistors, capacitor, voltage-stabilizing circuit and large capacitor; signal is input to grid of the through block capacitor C1, resistor R1 R2 form bias, source electrode grounded R3, amplified output drain tube; multiple single tubes, layer silicon dioxide insulating formed on each tube, 12 thermocouples are manufactured around electrode, layer, connected in series metal wire, two left as Seebeck voltage positive negative grounded, capacitor. According effect, waste heat produced work recycled converted into electric energy so perform storage self-powering; service life prolonged while radiating performance enhanced.
