The A1001-RU-1 from AmpliTech is a 5G Open-Radio Unit (O-RU) for n78 band from 3.55 to 3.7 GHz. It utilizes GaN power amplifiers along with 64 phased array elements for digital beamforming. This O-RU consists of three main parts: the first is the Radio Frequency Processing Unit (RFPU) which includes the antennas, high power amplifiers, low noise amplifiers, duplexers, and other functions. This part also contains highspeed data converters such as analog to digital converters (ADCs) and digital to analog converters (DACs). The second main part of the O-RU is the Digital Processing Unit (DPU) which supports the eCPRI and IEEE 1914.3 capability. The processing is performed in a field-programmable gate array (FPGA). The third part is highspeed Ethernet connectivity which is the interface to the rest of the O-RAN system and the Open Distribution Unit (O-DU).
The A1001-RU-1 has band preselect filtering, noise figure reduction at reception and provides a total EIRP of 43 dBm. It is available in a surface-mount package and is suitable for use in high & low-speed networks, IoT deployment, 5G backhaul deployment, and small cell deployment applications.
