The ALPHI PCIe-4QMC Carrier is a high-performance PCI Express® expansion card that hosts up to four single-width VITA 93 (QMC) mezzanine modules. It integrates high-speed I/O, signal-processing, and communication functions into workstation, server, or embedded PC platforms. Each QMC site connects through a dedicated PCIe Gen2 x4 interface via an on-board switch, providing exceptional throughput and modular flexibility. Air and conduction-cooled mechanical options support deployment in both commercial and rugged environments.
