Latching USB 2.0 Cable Assemblies
MilesTek’s latching USB 2.0 cable assemblies are ideal for military/aerospace applications where vibration is an issue, because unlike standard USB connectors, which rely on a friction fit, the latching USB Type-A connectors on these assemblies provide lock-down mating retention with any USB Type-A jack. Additionally, these cables feature low-smoke, zero-halogen (LSZH) cable jackets. LSZH reduces the amount of toxic and corrosive gases emitted during combustion.
Custom Low-PIM Coaxial Cable Assemblies
Pasternack’s line of low-PIM coaxial cable assemblies now consists of 160 standard configurations that boast PIM levels of < −160 dBc. These high performance, low-PIM cable assemblies are constructed with flexible, lightweight, UL910, plenum-rated, SPP-250-LLPL, RF coaxial cable which can operate in temperatures from −55°C to +125°C. These high quality cables deliver low insertion loss and excellent VSWR, are 100 percent RF and PIM tested and ship with the PIM test results marked on the cables.
18, 26.5 and 40 GHz Coax Test Cables
Times Microwave introduces its new Clarity Series of 18, 26.5 and 40 GHz coax test cables. Clarity boasts steel torque, crush and overbend protection with abrasion resistance yet does not compromise flexibility. The cable is ultra stable through 40 GHz with exceptionally low attenuation. An industry first includes an ergonomically designed, injection molded strain relief and Times’ new, SureGrip™ coupling nut to significantly improve the user’s everyday experience. Clarity is appropriate for use as VNA test port extension, R&D lab, production test and even system interconnect cables.
The Model 477Ka provides 700 W peak power at duty cycles up to 8 percent from 33 to 36 GHz. Particular emphasis has been placed on the generation of the output RF pulse shape. The RF output pulse width tracks the input 5 V video pulse. Internal power supplies are DC-DC converter designs operating at 50 kHz with fast loop response times so that output level variations are minimal for any PRF including a non-periodic or burst type PRF.
