Abstract:
An electronic device includes a first strip conductor formed from a first metal level over a substrate. A second strip conductor formed from a second metal level is located between the first strip conductor and the substrate. At least one of the first and the second strip conductors includes a stripline portion and a microstrip line portion.
Abstract:
An apparatus includes a dielectric slab having first and opposing second major surfaces. A planar antenna element is located on the first major surface. A via formed through the dielectric slab is conductively connected to the antenna element. A plurality of solder bump pads is located on the second major surface and is configured to attach the dielectric slab to an integrated circuit.

Abstract:
The object of the present invention is a low noise figure amplifier with a variable gain which comprises a cascode amplification stage comprising, serially mounted, a low-voltage MOSFET transistor installed as a common source followed by a bipolar transistor with high breakdown voltage installed as a common base. A resistor is placed between the bipolar transistor's collector and the grid of the cascode stage's MOSFET transistor, and the cascode stage is electrically powered through a choke.
Abstract:
An apparatus includes a spiral conductor, a first electronic device, and a second electronic device. The spiral conductor has first and second ends. The first end is a first port of the conductor. An intermediate portion of the conductor is a second port of the conductor. The second end is a third port of the conductor. The first electronic device has a first terminal connected to the first port and has a second terminal connected to the second port. The first electronic device is capable of carrying a current between the first and second terminals. The second electronic device has a third terminal that operates as a current source or sink. The third terminal is connected to the third port.
