Overview
Overview & Function
The RRU3959 (and RRU3959w) is an outdoor remote radio unit (RRU) used in distributed base station architectures.
It handles RF functions: modulation, demodulation, combining/dividing baseband and RF signals.
It uses software-defined radio (SDR) techniques, allowing mode configurations (multi-mode, multi-band) via software.
It has dual transmitter / dual receiver design to boost output power / capacity.
Physical & Interface Ports
From Table 1-1:
RF ports: 2 × DIN connectors (to antenna system)
CPRI ports: 2 × DLC connectors (connect to BBU)
Power supply port: 1 female connector (tool-less pressfit type) supplying –48 V DC (voltage range –36 V to –57 V)
RET port: 1 × DB9 (for Remote Control Unit, RCU)
Alarm port: 1 × DB15 (for external alarms)
Frequency Bands / IBW
From the frequency spec tables:
| Variant / Type | RX (MHz) | TX (MHz) | IBW (MHz) |
|---|---|---|---|
| RRU3959 P900 | 890 – 915 | 935 – 960 | 25 |
| RRU3959 E900 | 880 – 915 | 925 – 960 | 35 |
| RRU3959 1800 | 1710 – 1785 | 1805 – 1880 | 45 |
| RRU3959 2100 | 1920 – 1980 | 2110 – 2170 | 60 |
| RRU3959w 1800 | 1710 – 1785 | 1805 – 1880 | 75 |
Capacity (Single-mode / Multi-mode)
In GSM mode (900 / 1800), RRU3959 / 3959w supports up to 8 TRXs.
In UMTS (on 900 / 2100) mode:
• Without MIMO: up to 6 carriers
• With MIMO: up to 4 carriers
In LTE (FDD) mode:
• RRU3959 (1800 MHz) supports 2 carriers (bandwidth 1.4, 3, 5, 10, 15, 20 MHz)
• RRU3959 (2100 MHz) supports 4 carriers (bandwidth 5, 10, 15, 20 MHz)
• RRU3959w supports 2 LTE carriers (5, 10, 15, 20 MHz)
Multi-mode combinations (GSM + UMTS, GSM + LTE, UMTS + LTE, etc.) are supported (within band constraints)
Receiver Sensitivity
From the sensitivity table (Table 2-4)
GSM 900: –113.7 dBm (1-way), –116.5 dBm (2-way), –119.2 dBm (theoretical)
GSM 1800: –114.0 dBm (1-way), –116.8 dBm (2-way), –119.5 dBm (theoretical)
UMTS 900: –125.8 / –128.6 / –131.3 dBm
UMTS 2100: –126.1 / –128.9 / –131.6 dBm
LTE (FDD):
• 900: –106.3 / –109.1 / –111.8 dBm
• 1800: –106.6 / –109.4 / –112.1 dBm
• 2100: –106.9 / –109.7 / –112.4 dBm
Output Power
From various “typical output power” tables, and notes:
In GSM mode (900 / 1800), the max per carrier is 60 W (subject to licensing).
Under altitude conditions, output is de-rated: at 3,500–4,500 m → –1 dB; at 4,500–6,000 m → –2 dB.
For dual LTE carriers, power spectral density (PSD) matching is recommended (i.e. equal power per bandwidth).
The “typical” output per carrier depends on mode (GSM, UMTS, LTE) and number of carriers (see tables in the document)
Power Consumption & Input
Input: –48 V DC (–36 V to –57 V)
The RRU3959 / RRU3959w supports AC supply via external AC/DC module or OPM15M module.
Power consumption typical and maximum values are measured at 25 °C; load variation influences consumption.
Environmental & Other Specs
It is designed for outdoor installation, close to the antennas.
Operating temperature, protection, mechanical dimensions, etc. are part of the full spec, but I did not extract all from the sources I reviewed.
