Ultra-small crystal oscillators boast exceptionally low phase noise
The QTCC578 Series of ultra-miniature crystal oscillators are designed to meet the demand in high-performance, low-voltage applications with an exceptional phase noise floor of -155 dBc/Hz. The QTCC578 oscillators are offered with supply voltages of 3.3 Vdc and 2.5 Vdc. They are built using a miniature strip AT quartz crystal in a low-profile ceramic (5x7x1.5 […]
Rad-hard 14-bit ADC optimized for apps in space
Renesas is excited to introduce the ISL73141SEH ADC, delivering the industry’s highest performance for radiation-hardened space applications. The ISL73141SEH ADC is one of the key signal-path building blocks in long-duration geosynchronous/geostationary Earth orbit (GEO) communication satellites and manned spacecraft, including lunar space missions. By delivering the industry’s best dynamic and static performance, the new 14-bit […]
Chip-scale atomic clock produces super-stable frequencies
IQD is pleased to present its new chip-scale atomic clock (CSAC), ICPT-1. The ICPT-1 uses the Coherent Population Trap (CPT) method to obtain a very stable frequency. While common rubidium oscillators detect the atomic transition with the help of a rubidium discharge lamp (Rb lamp), the ICPT-1 uses a laser to induce quantum transitions. A […]
Zuken and Electro Magnetic Applications partner on cable harness design and EMI reduction
Zuken Inc., and Electro Magnetic Applications Inc. (EMA) have entered into a partnership to improve the accuracy of cable harness simulation models for complex electrical subsystems in aircraft and vehicles. The recent collaboration advances Zuken’s digital engineering initiative by enabling design teams to assess, simulate, and validate electrical and electronic designs before they reach manufacturing. […]
Multi-contact, high-current connectors for harsh operating conditions
Harwin has significantly raised the power levels that its product portfolio can support with the introduction of the Kona series. These 8.5 mm pitch connectors’ contacts are capable of delivering 60A of current. This means that applications such as battery charging can be addressed without having to split the current across multiple contacts. Among the […]
Rad-tolerant quad ARM Cortex space processor passes 100krad TID testing
Teledyne e2v has announced that its popular LS1046-Space processor has now passed stringent total ionizing dose (TID) radiation tests, achieving 100krad resilience. This multi-core device, which features four 64-bit Arm Cortex A72 processing cores, was able to operate as normal after the TID tests had been undertaken. These results complement those previously obtained in terms […]
The Iridium global satcom system, Part 5: Advances and competition
This worldwide satellite-based communications system went from dream to reality in a decade but quickly failed in the market; its revival took persistence and luck, plus a new customer base. Of course, there were also significant technological advances required in many areas, including designing and building longer-life electronics despite the unavoidable effects of space radiation […]
The Iridium global satcom system, Part 4: Lessons learned
This worldwide satellite-based communications system went from dream to reality in a decade but quickly failed in the market; its revival took persistence and luck, plus a new customer base. Today, Iridium is a viable mobile, satellite-based, which handles voice and data. As with standard cellular systems, its users have little or no idea of […]
The Iridium global satcom system, Part 3: Very nearly crash and burn
This worldwide satellite-based communications system went from dream to reality in a decade but quickly failed in the market; its revival took persistence and luck, plus a new customer base. Iridium’s launch, crash, and nearly burn (literally) The Iridium communications service was initiated on November 1, 1998, with a call by then-Vice President Al Gore. […]
