A disk is a data storage medium consisting of a flat, circular, magnetic surface on which information can be recorded. You will receive several disks with your computer. These already contain information and programs, and are ready to use.
Blank disks can be used to store your own information and programs, but these disks must be formatted before they can be used.
Disks which contain important information can be write-protected. This means you can read from but not write to the disk, making it impossible to write accidentally over information. Your disks can be write-protected - instructions are included in each box of disks.
Ответьте на вопрос
Why are disks with very important information called write-protected?

Power dividers serve a multitude of circuit and system applications, from amplifiers to radar receivers. The power divider is housed in a hermetic enclosure with stainless-steel female SMA connectors. As these stripline power dividers feature such small physical dimensions, more than 20 power dividers can be fabricated from a single substrate. Unit-to-unit amplitude tracking is specified as better than ±0.6 dB, while standard unit-to-unit phase tracking is better than ±6 deg. at 18 GHz.
Insertion loss (in excess of expected power-division losses) is less than 2.0 dB.
The four-way power divider boasts amplitude balance of better than ±0.4 dB. Phase balance is better than ±5 deg. Designed to handle input power levels to 1 W CW, the power divider supports wide-dynamic-range signal processing.

For use in broadcast and communications satellite receivers, the series of microwave local oscillators feature the smallest, lightest designs in the industry, weighting 4.4 g and measuring 7.5 mm tall. They offer a 1.9 cc volume. There are six models; samples are available. This one operates at 10.678 GHz. The 2nd covers 11.200 GHz, the 3rd works at 11.300 GHz and the 7th accommodates 10.750 GHz. The 8th works at 10.873 GHz, the 9th handles 10.990 GHz. The excellent performance eliminates the need to adjust the high frequency. As a whole, the modules make it possible to create a miniature outdoor unit for satellite broadcasting. They are suitable for converters in flat antennas, and mount easily on converters.

A compact noise filter for large equipment accommodates currents as large as 100 A or more because it incorporates flat, vertically wound copper wire. Samples will be available in October. To wind the straight copper wire, the engineers used an automatic winder, creating double coils adjacent to each other. This raises the density of the electromagnetic coupling and results in 5-to-10-fold improvements in the current super-position characteristics of inductance. For easy assembly, the coil combines with UU or UI ferrite cores. Offering voltage rating for AC 250 V single-phrase or AC 450 V triple-phase, the filters attain a current rating of 50 to 150 A. The 80 A version measures 150 €240 €90 mm.
