Introduction:

● The ORAN-RRU is an outdoor remote radio unit. It is the radio frequency (RF) part of a distributed base station and can be located near antennas.  

● Adopting an innovative design, ORAN-RRU is able to work in 2TX and 2RX mode and therefore supports higher output power and larger carrier capacity.

● It can support 4G/5G all of 3GPP Frequency, include B1/B3/B5/B7/B8/B20/B28/B40/B41/B68/N77/N78/N79 etc

 

Highlights:

1. Mechanical Design

● Smaller and Lighter(-4T4R/SBP: 13L/15KG; -8T8R/MBP: 25L/25KG)

● PA sub board adopts  golden finger  technology, which  occupies a small PCB  area

● Integrated wireless  cable design, simple  process (traditional  scheme is multi  module design,  requiring cable  connection)

● FPGA heat dissipation  adopts soaking design  and VC soaking plate  process

 

2. GaN+DPD(-30%~35% overall efficiency)

● Gan is at least 5% more  efficient than traditional  LDMOS,

● Gan has a larger bandwidth  than traditional LDMOS, and  can be used as a wider band  or multi band device

● Integrated power supply high  efficiency, up to 94%

 

3. RFSOC+DFE

● The total FPGA power is  reduced by 50%

● Integrated core, simplified design

● Multi-Band, Multi-Mode  Operation for Flexibility and  Scalability

● Complete Adaptive SoC for  Fully Software-Defined Radio

 

4. Cavity Filter & Antenna

● Low insertion loss

● High out of band  suppression

● High power

● Low intermodulation

● Good frequency selectivity

● Antenna Integration
