STMicroelectronics has expanded its European Rad-Hard aerospace
portfolio with the addition of four amplifiers, which have
achieved official QML V qualification.
"According to the Satellite Industry Association,
the global satellite industry is healthy and growing. Global
revenues totaled $168.1 billion in 2010, for an 11.2 percent
average annual industry growth rate over the past 5 years
1," said Alberto De Marco, ST General Manager, High-reliability
and Standard Products Division. "With many of the activities
of our lives depending on satellites--entertainment, navigation,
communication--their functioning and reliability is extremely
important, making it critical for electronic components,
like those we are introducing today, to withstand the high
levels of radiation found in space."
ST claims it has become a reference in the Aerospace industry
by establishing its standard hardness to ionizing radiation
at 300 krad (Si) (Total Ionization Dose hardness, known
as TID), including low dose-rate irradiation, allowing the
company to be the first supplier to offer Radiation Hardness
Assurance (RHA)-qualified products with Enhanced Low Dose
Rate Sensitivity free (ELDRS-free) integrated circuits.
ST is also providing the highest hardness to the damage
caused by heavy ions, with Single Event Latch-up (SEL)-free
and Single Event False Interrupt (SEFI)-free components.
The extension of the product family includes the following
- RHF484, a quad version of the RHF43B and an alternative
to industry-standard products. Packaged in a Flat-14W, their
QML V qualification was achieved in August 2011.
- RHF310 and RHF330, and very low power 5V op amps ideally
suited to a wide range of signal-conditioning applications.
The 120 MHz and 1.0GHz versions are already QML V qualified.
Another device, the 550 MHz RHF350 is expected to be qualified
in Q4 2011.
ST says its analog space devices have been designed with
special attention to Single Event Transients and are fully
characterized with low amplitude, small duration glitches.
All of ST's rad-hard are designed using BICMOS technologies
to consume low power. These devices are added to the European
Product Part List (EPPL) once space qualified, with the
active support of the Centre National d'Etudes Spatiales
