The customer wants to capture the output of some silicon diodes looking at a laser target. The typical signal is anywhere from 20mv to 1V in amplitude and 0 to 15ns in length. There are up to 16 of these diodes that are looking at the same target. Each diode has a different filter so the post-trigger depth and amplitude-scale must be user-adjustable. Their main interest is to sample and digitize the signals for archiving, with later retrieval and plotting. Fancy software is not needed for display as the data is gathered in the field by the technicians. Later, the data typically would be formatted into a matrix and manipulated by a scientific program. The trigger for all channels is a single pulse from the laser facility - not 16 independent signals. Products & Services
PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies.
Specialty diodes are specialty or proprietary products and accessories related to diodes.
Current limiting diodes (CLD) regulate current over a wide voltage range. There are several types of current limiting diodes (CLD). Examples include a current regulator diode, constant current diode, and current limit diodes.
Step recovery diodes produce an abrupt turn-off (step) time by allowing a very fast release of stored charge when switching from forward to reverse bias, and from reverse to forward bias.
Diode arrays are composed of multiple discrete (usually unconnected) diodes on a single silicon chip. Diode arrays are important semiconductor products because they save assembly time and improve reliability over individually packaged diodes. In general, diode arrays use four or more diodes in a single package.
