Abstract: A radio-frequency power amplifier includes a multiple-FET chip that is flip mounted on a connection region of a substrate. An input impedance-matching network is also mounted on the substrate. The network includes a coplanar waveguide having an elongate waveguide signal conductor for each gate terminal on the FET chip with a distal end spaced from the connection region and a proximal end in the connection region. The distal ends are connected to a single base input conductor. The proximal ends are flip mounted to respective ones of gate terminals of the FET chip. A capacitor couples each of the input signal conductor distal ends to an adjacent ground conductor. The signal conductors and capacitors provide a selected impedance at a selected frequency. The capacitors may be on a separate chip flip mounted to the waveguide signal and ground conductors, and may be formed as coplanar waveguides with open-ended signal conductors. An output coplanar waveguide includes, for each drain terminal, an output signal conductor having an end in the connection region that is electrically connected to the flip mounted FET chip.

Inventor: HUANG HSIN-ERH
IPC: H01M10/26
Filed: 1998-01-06
Granted: 2001-04-01
Abstract: This invention provides the pulverization process for fabricating hydrogen storage alloys used in negative electrodes of nickel metal hydride batteries. The conventional mechanically roughly shattering or finely grinding is not used in this process and only hydride-dehydride pulverization method is used. Under appropriate control of hydrogen absorption temperature (< 100 DEG C), pressure (1 to 50 atm) and time, the hydrogen storage alloys are directly pulverized into powder, which is required for fabricating negative electrode plates of nickel metal hydride batteries, after one time of hydrogen absorption process. The particle-size distribution of powder is concentrated and the ratio occupied by powder having size smaller than 100 mu m is more than 90%. By using this invention, the parameters of hydride-dehydride pulverization process can be controlled to change particle-size and distribution of powder. Therefore, the requirements of electrical design for each type of nickel metal hydride batteries can be fulfilled so as to raise the performance of nickel metal hydride batteries.

Abstract: The present invention relates to an improved demodulator for locking onto and tracking a carrier. Harmonic frequencies are occasionally generated by demodulation circuitry. When this occurs, the harmonic frequencies can interfere with the demodulator's locking and tracking functions, especially if the harmonic frequencies are near a down converted carrier's frequency. A system and method are disclosed which provides an offset to a frequency synthesizer whose output frequency is used to down convert the carrier. The offset alters the frequency of the down converted carrier so as to shift it away from the interfering harmonics. In this regard, the demodulator is enabled to lock onto and track a carrier when previously not possible.
