  • Patent number: 5532667
    Abstract: A ferromagnetic material (18,20) in ink or tape form is sinterable using a same firing profile as and has approximately the same thermal shrinkage characteristics as low-temperature-cofired-ceramic (LTCC) tape, and is chemically non-reactive therewith. The ferromagnetic material (18,20) is applied to the surfaces of LTCC tape sheets (12,14,16) to form desired elements such as cores for inductors (22) and transformers and magnetic shields. Ferromagnetic vertical interconnects (vias) (54) can be formed by punching holes (56) through tape sheets (46) and filling them with ferromagnetic ink. The tape sheets (12,14,16) and ferromagnetic elements (18,20) are laminated together and cofired to form an integral structure (10). Ferromagnetic and non-magnetic components (114) can be fabricated separately and inserted into cavities (104a,-106a,108a) in tape sheets (104,106,108) prior to cofiring.

  • Patent number: 5162963
    Abstract: A power supply including a source of AC power, a filter including inductive elements, and rectifying circuitry. Where the AC source comprises a sinewave source, the filter includes inductive and capacitive elements; and where the AC source comprises a square wave source, the filter includes only inductive elements.

  • Patent number: 5121084
    Abstract: A balance circuit for an amplifier circuit having 2.sup.M amplifiers serially biased across a supply potential node and a common potential node, where M is an integer greater than 0, and having respective 2.sup.M -1 interstage bias nodes and voltages between the amplifiers which are driven by respective input drive signals provided by 2.sup.M -1 2-way power splitters. A voltage reference circuit provides as to each power splitter first and second reference potentials respectively associated therewith. A plurality of control circuits are associated with respective power splitters and interstage nodes. Each control circuit is responsive to the associated first and second reference potentials and the interstage bias node for controlling the signal levels of the first and second drive signals provided by the associated 2-way splitter as a function of the associated interstage bias potential relative to the first and second reference potentials.

  • 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.

  • Patent number: 4972309
    Abstract: A DC to AC sinewave converter having an FET with its gate terminal coupled to a switching signal which turns the FET on and off. A pair of parallel, oppositely conductive diodes couples the drain terminal of the FET to a resonant circuit that is responsive to a source of DC voltage. A clamping diode is connected between the parallel diodes and the source terminal of the FET for preventing the drain and source terminals from being reverse biased.

  • Patent number: 4841429
    Abstract: A rectifying power supply having circuitry for providing AC power, a plurality of capacitors responsive to the AC power for providing DC isolation and for providing capacitively coupled AC power, and a plurality of rectifying circuits responsive to the capacitively coupled AC power for providing respective DC outputs. The outputs of the rectifying circuits are coupled in series or in parallel.
