Dev kit for space-qualified FPGAs with QML qualification
Microchip is aiming at satellite designers with a development kit built around its radiation tolerant RT PolarFire FPGAs, for which MIL-STD-883 Class B qualification has been gained and both Class Q and Class V qualification have been sought. October 2023 update: RT PolarFire FPGA’s are now QML (qualified manufacturers list) Class Q qualified, as designated by the US Defense Logistics ...
EPC aims high with 300V space-grade GaN power transistor
EPC Space has introduced radiation-hardened gallium nitride devices for space-borne power converters and other rugged environments. There are two devices, one rated at 200V and the other at 300V: EPC7020G – 200V, 14.5mΩ, 80A (pictured) EPC7030G – 300V, 32mΩ, 50A “Applications including power supplies for satellites and space mission equipment, motor drives for robotics, instrumentation, reaction wheels and deep space ...
A dozen 26GHz coax connections in a single rugged housing
Lemo has put a dozen 26.5GHz coax contacts inside a high-reliability circular connector housing, sealed to IP68 when mated. Called LM.232, its signal paths are 50Ω, with a VSWR of ~1.2 from 5 to 15GHz, peaking to 1.4 at 18GHz. The contacts are designed to be terminated on LMR-100A, Multiflex 86, RG-174/U, RG-188 A/U or RG-316/U flexible cables. Attachment is ...
More power/signal contact options for Harwin’s high-rel Gecko-MT connectors
Harwin has expanded the contact layout options of its high-reliability Gecko-MT connectors. There are six additional contact arrangements, with 2 to 6 power contacts and 4 to 24 signal contacts. To give an idea of size: the connectors are 5mm wide. These new ones are non-symmetrical, with 10A (max) power contacts at one end and 2A (2.8A max in one ...
1.27mm pitch connectors are tough for military and aerospace
Glenair’s QPL 83513 Micro-D connectors feature the company’s high-density micro TwistPin contacts set on 1.27mm (0.05 inch) centres, with from 9 to 130 contacts, and are designed for high reliability in taxing environments. “Thanks to special material selection, fabrication and heat treating techniques, TwistPin contacts resist stress relaxation for up to 1,000 hours at 125°C,” according to Powell Electronics, which ...
Miniature connectors mate with Glenair Mighty Mouse and Amphenol 2M
TopFlite ‘M&M Connector’ series provides “100% intermateability with existing micro-miniature connectors in the market, including Glenair Mighty Mouse and Amphenol 2M”, according to the Florida company, and “offer performance and durability comparable with MIL-DTL D38999 connectors in a miniature package”. It has six different coupling styles with contact options including crimp, solder and printed circuit board, and options include EMI/EFI ...
100V 3.9mΩ GaN transistor is rad-hardened
EPC has announced a 100V 3.9mΩ radiation-hardened GaN HEMT. Called EPC7018 it comes in a 13.9mm2 chip-scale package (the ‘flag’ in the image) and can handle pulses up to 345A. The total dose radiation rating is greater than 1Mrad, and SEE immunity for LET of 85MeV/(mg/cm2). “EPC7018 offers designers a high power, low on-resistance device enabling a new generation of power conversion and ...
Tough compact connectors for USB 3, HDMI, Ethernet and more
For higher pin-count busses, Fischer has added a larger connector to its MiniMax Series of miniature rugged high-reliability connectors. The connector has a 14mm diameter body (Fischer size 10) and comes in two versions so far: 12 signal and power contacts offering USB 3.2 Gen 2 (10Gbit/s, 1m) and up to 8A, for high-speed intercom boxes and next-generation hubs 30 ...
GaN power transistor drivers for military and high-rel
Teledyne e2v HiRel has introduced pair of isolated 650V 4A gate drivers aimed at GaN power transistors, offering 2.5kVrms isolation and 100% ac-dc testing at -55 to 125°C. TDGD271 is a single channel driver in 8pad SOIC, while TDGD274 is a dual channel driver in 16pad SOIC. “The TDGD27x family devices are ideal for isolated mosfet, IGBTand SiC or GaN HEMT gate ...
