  • Microelectronic variable inductor
    Patent number: 4035695
    Abstract: A conductor provided on an insulating support has a portion which forms an inductor. Various components are connected to the conductor, as by soldering, to provide an electronic circuit suitable for a particular application. The conductor portion which forms the inductor has parallel branches and the value of the inductance can be changed by selectively open circuiting the branches. This can be accomplished after the components are connected and the complete circuit is tested to determine whether a change in the inductance value is required. The branches can be selectively open circuited by removing a portion of the cnductor by a laser beam which does not substantially heat the structure, with the heat which is produced being highly localized. Accordingly, this does not soften the solder connections of the components and there is no damaging effect on the circuit.

  • Radio frequency power amplifier constructed as hybrid microelectronic unit
    Patent number: 4001711
    Abstract: A radio frequency power amplifier includes a flat ceramic substrate having a conductive coating on one side and a plurality of conductors on the other side arranged in a predetermined pattern. At least one conductor is connected through the substrate to the conductive coating which is grounded. A plurality of components are connected to the conductors on the substrate including a transistor die, chip capacitors, air wound coils, a chip inductor and resistors. Conductors on the substrate are of a configuration to provide spiral inductors, some of which are connected in series with the air wound coils, which have tuning segments adapted to be severed to control the inductance after assembly of the components. Conducting bridges are also provided to join conductors which are spaced from, and insulated from, an intermediate conductor.
