PX-702
Vectron offers a small footprint High Temperature Ceramic SMD Crystal Oscillator (PX-702) product platform for extreme environment
applications. In addition to its wide operating temperature range, PX-702 HTXO is also ideal for high shock & vibration applications. PX-702
HTXO is also designed to exceed 3000g shock and 36g vibration levels of the demanding MIL-STD-883 requirements.
Vectron’s vertical integration in the following technical areas ensures the ability to design and manufacture state of the art high temperature
frequency control products:
BAW & SAW Design & Fabrication to produce high quality resonators.
RF Oscillator Circuit Design.
Established 250°C High Temperature Electronics Packaging Expertise.
Established 250°C High Temperature Electronics Assembly & Test Expertise.
Environmental Screening.
Vectron’s manufacturing processes, from quartz resonator fabrication to oscillator electronics assembly and test, are painstakingly controlled
via ISO and SPC procedures. Vectron fabricates high temperature quartz resonators using proprietary manufacturing processes designed
specifically for high temperature and harsh environment applications. In order to ensure high reliability in the field, critical electrode
metallization and testing processes are conducted inside state-of-the-art Class 1K cleanrooms, while oscillator assembly is conducted in Class
10K cleanrooms. All high temperature oscillators are 100% tested before delivery.
