Description

---

The low noise receiving unit MRA9008 is used in GSM base station. It provides high gain and low intermodulation level. DC power supply and control signals are sent through the RF cable using a bias tee.
The unit is suitable for outdoor tower mounting to improve uplink diversity performance. The monitoring board built-in enables RF signal by-pass in case of amplifier failure.
