Optical transceiver technology devices have shown an increase on performance and a reduction in SWaP (Size, Weight, and Power) by their inclusion in Very High Throughput Satellites (VHTS) payloads. To ensure their practical use in space applications, they need a compact package, low power consumption, and highly reliable.

The pre-procurement phase combines the EEE parts state-of-the-art analysis, risk analysis and component ownership cost optimization with regards to the mission requirements, design criticality and budget. In order to achieve this, the project manager leading a multidisciplinary team must find the optimal balance between component information availability (traceability, materials, testing, previous use…) and minimum tests to perform, reaching an acceptable level of reliability covering the technical, schedule and costing constraints.

The early identification of parts affected by an alert is important to avoid the use of that part in the design if an alternative is available. In the case the part has already been procured, it is important to know about the alert to see which solutions are available or the specific impact of the alert on our application.

An optocoupler, also known as an optoisolator or photocoupler, is an electronic device made up of an LED emitter combined with a photodetector, separated from each other in proximity. There are many types of photodetectors, most of which are variations on a photodiode or phototransistor.

Current-sensing techniques are intrusive, meaning that somehow they will affect the system performance. It’s usually necessary to insert “something” in the middle of the path that goes from the power source to the load through which the current that we need to monitor flows.

Semiconductors are essential for any digital product (on the rise) in practically all industrial sectors. Their demand has multiplied due to changes in habits during the pandemic. Worldwide shortages, including raw material ones, continue to heavily impact production and manufacturing capacity leading to tight supply, extended lead times, and increased pricing, and production stoppages in some manufacturing plants in industries like the automotive one, but not only worldwide level.
