Introduction
The commercial satellite industry has requested that smaller, lighter, less
expensive oscillator products with shorter lead times be made available
for minisatellites, microsatellites, nanosatellites and picosatellites. In
addition some newer satellite programs are being created for short term
space lives and do not need oscillators with the assurance of a 15-20 year
life span.
Q-Tech Corporation, the industry leader in both Class B and Space Rated
hybrid crystal oscillators is pleased to advise that we have created a
special category of product designated as Class B+ for these applications.
See website for link to RAD test data.
We have created these Class B+ products for the discriminate user’s
applications and needs using our small form MIL QPL Class B oscillators.
You, the customer, can now pick and choose the style of clock oscillator
you wish, whether you want a 100kRad (Si) High Dose Tolerant NSC
54ACT3301 (FACT) or a standard Class B qualified die, a swept quartz
space qualified crystal or a Class B cultured quartz crystal and/or a
combination thereof in an oscillator product that otherwise utilizes Class
B qualified passive devices. Q-Tech offers several different screening
options to allow you to choose the screening plan that best suits your
needs.
Q-Tech Corporation does not guarantee the specific radiation hardness
of its Class B+ products but will provide the necessary active device
component traceability to allow you to make your own decision and do
your own testing and evaluation based upon your specific needs and
requirements.
Initially we will begin this product offering in three of our leading
miniature clock oscillator product lines: QT78 (M55310/27, /28 & /30) ,
QT88 (M55310/33 & /34) and QT92 (M55310/37 & /38). Product will
be available in 5.0 and 3.3 Vdc from 450kHz to 85MHZ. Please consult
the factory if you would like to know if this option is available in other
standard Q-Tech Class B product lines or if you have any other specific
oscillator needs that we can help you with.
