Huawei RRU5909 (PN: 02311TBA) — 900 MHz 2T2R Remote Radio Unit

1. Product Overview

The Huawei RRU5909 is a software-defined radio (SDR) remote radio unit that supports multi-standard operation and flexible reconfiguration via software.
It is typically installed close to the antenna in macro base station deployments to reduce feeder loss, improve coverage, and increase network capacity.
Compatible with Huawei DBS3900 / DBS5900 distributed baseband platforms.

2. Radio and Frequency Specifications (Band 8 / 900 MHz Version)

Typical carrier capacities (reference values)

5. Mechanical and Environmental

6. RF and Antenna Interfaces

• RF Ports: 2 (for 2T2R configuration); connector type 7/16 DIN or 4.3-10 depending on region.

• Supports: RET antennas and TMA (Tower Mounted Amplifier).

• Best Practice: Use factory-certified jumpers (≤ 6 m) to minimize PIM and loss.

7. Typical Application Scenarios

• 900 MHz macro coverage layer for deep indoor penetration and wide-area coverage.

• Multi-RAT co-deployment: GSM + UMTS + LTE (+ NB-IoT) in shared sites.

• Network modernization: Upgrading existing 2G/3G sites to LTE or NB-IoT without replacing the baseband unit.
