  • Patent number: 6204825
    Abstract: A hybrid shield and antenna unit for a printed circuit board is disclosed. A shielding enclosure for providing RF and electromagnetic shielding of the electronic components of a circuit board is integrated with an antenna as a single unit. The hybrid shield and antenna combination may be fabricated as a single unit to provide for reduced steps in the manufacturing process thereby leading to improved economy. The hybrid shield and antenna includes a shielding enclosure for providing RF and electromagnetic shielding of an electronic component, and an antenna disposed at an end of said central enclosure, wherein the antenna and the central enclosure comprise a single continuous unit.

  • Patent number: 5153469
    Abstract: A biasing network for use in conjunction with a mixer employing field effect transistors which provides for minimum conversion loss over a range of process and temperature conditions. The biasing circuit includes a first field effect transistor having a small gate periphery which is configured as a current source, a second or reference field effect transistor having a gate periphery substantially equal to the gate peripheries of the transistors in the mixer to which the biasing circuit is providing DC biasing voltages and a voltage divider which is functional in defining operating conditions for the reference transistor.
