Silex SX-SDPAC is a dual-band 1x1 802.11a/b/g/n/ac plus Bluetooth 4.1+HS “Smart Ready” SDIO SiP module based on the Qualcomm Atheros QCA9377 System-on-Chip (SoC) for portable battery operated electronic devices. The SX-SDPAC brings 802.11ac throughput and range to portable devices including patient monitors, printers, handheld terminals and more.

The SX-SDPAC is a System-in-Package (SiP) designed to be mounted directly on the device PCBA. This design approach minimizes cost by eliminating extra materials (i.e. PCB and connectors) and labor associated with a radio module or card.
