  • High speed PIN diode driver circuit
    Patent number: 10594312
    Abstract: An apparatus includes a first circuit and a second circuit. The first circuit may be configured to inject charge into an I-region of a PIN diode in response to a first state of a control signal. The second circuit may be configured to remove charge from the I-region of the PIN diode in response to a second state of the control signal. A radio frequency switching time of the apparatus is generally about two orders of magnitude lower than a carrier lifetime of the PIN diode.
    Type: Grant
    Filed: February 14, 2019
    Date of Patent: March 17, 2020
    Assignee: MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.

  • Particle-based time indicator and method for its use
    Publication number: 20060274606
    Abstract: A particle-based time indicator that indicates the passage of time through the settling of particles suspended in a liquid. The indicator may consist of a container of fluid and particles of different ranges of sizes. The container may have one or more timing marks for viewing.
