  • Patent number: 5661647
    Abstract: Electronic VHF/UHF power conversion circuitry is manufactured using the benefits of low temperature co-fired ceramic substrates to provide interconnection between the discrete components of the power conversion circuit, and integrate various non-semiconductor devices into the body of the low temperature co-fired ceramic structure, such as resistors, capacitors, inductors and transformers. Use of a low temperature co-fired ceramic structure as a substrate on and within which VHF/UHF power conversion circuitry is formed allows selection of various conductive and resistive inks to precisely form interconnection circuitry and selected non-semiconductor components which improves the stability and reduces the cost of VHF/UHF power conversion circuits.

  • 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.
