AMARI PCIe SDR 100 4x4 Card

AMARI PCIe SDR 100 4x4 is a software defined radio (SDR) card based on AD9361 2x2 RF transceivers. It supports MIMO 4x4, FDD and TDD operations in any frequency between 500 MHz and 6GHz. It has an integrated GPS for accurate time and frequency synchronization. The cards can be easily chained thanks to a provided cable allowing clock and PPS propagation in between the cards. This will facilitate testing of higher MIMO layers and carrier aggregation. The total bandwidth of the card is 100 MHz, and its output power is around 12 dBm depending on the frequency used. The card requires at least gen 3 PCIe slot. This RF is used in AMARI Callbox Advanced, AMARI Callbox Ultimate, AMARI Callbox Extreme, AMARI UE Simbox E Series and AMARI UE Simbox MBS Series products.

The software utilized in all AMARI UE Simbox Series products remains consistent. The primary distinction among the Simboxes lies in the hardware specifications, including CPU power and the number and type of SDRs. These differences result in variations in capacity, covering aspects such as the number of cells, cell bandwidth, MIMO layers, and the quantity of emulated UEs.

Specifically designed for small cell gNodeB testing, the AMARI UE Simbox E Series offers four different variants supporting 1, 64, 128, or 256 UEs. Additionally, it supports 5G NTN as a software option.

For those interested in 5G macro base station testing, explore the capabilities of the AMARI UE Simbox MBS.
