  4. 4. Integrated Variable-Gain and CMOS Millimeter-Wave Amplifiers

    Author : Mohammad Anowar Masud; Chalmers University of Technology; []

    Abstract : Variable Gain Amplifier finds extensive use in the high frequency demonstrators specially those operating in the millimeter-wave regions and beyond where the incoming RF signal level can have wide variations. To maintain a constant signal level an IF VGA has been designed that can offer a dynamic variation of gain as much as 45 dB together with a high maximum gain and a low noise figure. READ MORE

  5. 5. Novel RF MEMS Switch and Packaging Concepts

    Author : Joachim Oberhammer; KTH; []
    Keywords : 0-level packaging; adhesive bonding; BCB; benzocyclobutene; bond strength; contact printing; film actuator; glass lid encapsulation; glass lid packaging; helium leak test; hermetic packaging; hermeticity; high isolation switch; low stress silicon nitride; low volt; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Radio-frequency microelectromechanical systems (RF~MEMS) are highly miniaturized devices intended to switch, modulate, filter or tune electrical signals from DC to microwave frequencies. The micromachining techniques used to fabricate these components are based on the standard clean-room manufacturing processes for high-volume integrated semiconductor circuits. READ MORE
