摘要： A heat-sink assembly is configured with two parts to grip a light-emitting element and produce a transverse force urging a surface of the light-emitting element toward a surface of the heat-sink assembly, which conducts heat away from the light-emitting element. Fastening mechanisms and a fulcrum inter-connect the heat-sink parts and produce the force that grips the light-emitting element. A configuration of the heat-sink parts creates a semi-enclosed space accessible through a gap. A configuration of elastomeric gaskets within the semi-enclosed space protects a portion of the space from intrusion of liquids or other environmental influences. Configuration of the heat-sink parts to form a recess in the heat-sink assembly provides protection of the light-emitting element from mechanical damage, and the recess may contain transparent materials that further protect the light-emitting element from detrimental environmental influences.

摘要： A protective coating useful as a passivation layer for semiconductor devices incorporates a thin film of an amorphous diamond-like carbon. In one implementation, a thin film of amorphous silicon is deposited over the carbon material. The semiconductive passivation coating prevents electrical shorts, dissipates charge build-up and protects against chemical contamination.

摘要： A rectangular pulse generator system is operatively configured to generate a generator output signal, the generator output signal formed as a base rectangular waveform gated by a modulating rectangular waveform, the base rectangular waveform having a first frequency and the modulating rectangular waveform having a second frequency less than the first frequency. A low-pass filter coupled to the rectangular pulse generator system is configured to receive a filter input signal representative of the generator output signal and to produce a filter output signal representative of the filter input signal. A voltage-controlled current source coupled to the low-pass filter generates a drive signal conducted by at least one LED producing a light flux determined by the current level of the LED drive signal. Methods are devised for calibration and for setting the average light flux level.

摘要： A multiplexer circuit may include a first-frequency-quarter-wavelength transmission line extending between a junction between a common terminal and a second-frequency terminal, and a first-frequency low-impedance circuit electrically directly connecting the first transmission line to a circuit ground. In some examples, a second-frequency-quarter-wavelength transmission line may extend between the first transmission line and a third-frequency terminal. A second-frequency low-impedance circuit may electrically directly connect the second transmission line to the circuit ground. The first and second transmission lines and the first and second low-impedance circuits may provide a third-frequency transmission line. A further second-frequency low-impedance circuit may electrically couple the second terminal to the first transmission line. A third-frequency low-impedance circuit may electrically couple the second terminal to the circuit ground. The first-frequency, further second-frequency, and third-frequency low-impedance circuits and the first transmission line may provide in combination a second-frequency transmission line.

摘要： A method and apparatus for coupling a conductor-based transmission line, such as a strip transmission line, to a waveguide. The transmission line may be separated from a corresponding conducting ground plane by a first dielectric substrate layer. The ground plane may be adhesively coupled to a portion of the waveguide, and may be offset from the interior of the waveguide, so that adhesive squeezed out between the ground plane and the waveguide may be at least partially shielded from the waveguide, and thus does not significantly perturb electromagnetic signals within the waveguide.

摘要： First and second slotlines are mounted on an electrically insulating substrate having a planar face with a connection region. Each slotline has first and second, spaced-apart coplanar conductors that extend into the connection region. A fifth, ground conductor, also mounted on the substrate face, is spaced from and coplanar with the first and second slotlines and has a proximal portion in the connection region. A chip circuit includes first and second field-effect transistors (FETs) flip mounted in the connection region to all five conductors. The gates of the FETs are connected to the first slotline for receiving an input signal. The drains are connected to the second slotline for outputting the signal amplified by the transistors. The sources of the FETs are connected to the fifth conductor. This general configuration can be modified for use as an amplifier, oscillator, frequency multiplier or mixer. The slotline may divide into parallel slotline portions for providing plural circuits in parallel with distributed impedance matching. A slotline may loop back from the connection region to provide a choice for impedance matching, and a portion of the fifth conductor may extend between slotline conductors to provide capacitive coupling.

摘要： 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 coplanar transmission line conductors, and may be formed as coplanar waveguides with open-ended signal conductors or as overlay capacitors. 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. This waveguide also has a length selected to provide desired impedance matching.
