SPX-PHASE
Add to Info-List

Quad M.2 WWAN Module Carrier, 4-Way Antenna Signal Combiner/Splitter

The SPX-PHASE is a peripheral slot card for CompactPCI® Serial systems. The board serves as a quad carrier for M.2 3042 style WWAN modules, e.g. 3G or 4G (LTE) modems, and forthcoming technologies beyond 4G. Four front panel Mini SIM card slots are provided, related to the M.2 module sockets.

The R/F module connectors are strapped to an on-board 4:1 R/F combiner circuit. While maintaining good isolation between the inputs, the combiner has its low loss R/F sum port wired to the SMA type front panel antenna connector, for minimum external antenna cabling effort.

As an option, the SPX-PHASE can be equipped with a custom specific 8HP or 12HP front panel, providing up to six or twelve more antenna connectors, which would be strapped directly to the module W.FL type R/F jacks, hence bypassing the R/F combiner circuit. An on-board PCI Express® to quad USB 3.0 5Gbps controller is used as upstream connection from the M.2 sockets to the CompactPCI® Serial CPU card.

The SPX-PHASE is well suited especially for higher throughput applications which require WWAN bandwidth aggregation.
