  • VHF DC-DC power supply operating at frequencies greater than 50 MHz
    Patent number: 4980810
    Abstract: A DC to DC power supply including an RF driver circuit for providing an RF output drive signal having a frequency greater than about 50 MHz, power amplifier circuitry responsive to the RF output drive signal and a DC voltage supply for providing an amplified AC output, and an impedance transforming circuit such as a balun transformer for transforming the AC amplified output to an impedance transformed AC signal. The transformed AC signal is provided to a rectifying circuit which provides a DC output. A feedback regulation control circuit provides for regulation of the power supply output voltage. The DC to DC power supply is advantageously implemented with printed microstrip or stripline passive components.
