QPS Attenuators Qualified Parts for Space (QPS) Attenuators Cinch Connectivity Solutions Midwest Microwave has used its experience of designing custom space parts for many space programs and QPL parts for many military programs and introduces standard line of Qualified Parts for Space (QPS) attenuators. QPS attenuators are built using materials that meet or exceed 1% TML (Total Mass Loss) and 0.1% CVCM (Collected Volatile Condensable Materials) requirements as tested per ASTM E595. QPS attenuators were qualified using qualification testing guided by MIL-DTL-3933 level T qualification. They are available with three standard screening options with various severity of screening. Custom screening options are available on request.
