Introduction
MTI’s G07CRH-48-01B is
a 2x67W LTE TRDU
which has two RF transmitters, two receivers and double duplexer filter. It
is packaged in a single shelf-mounted module and is deployed in CPRI-compliant basestation networks.
The TRDU features in-house developed dynamic digital power amplifier linearization technology which efficiently
processes LTE transmissions, enabling:
processes LTE transmissions, enabling:
• High PA efficiency, resulting in low power consumption (475 W)
• Low EVM waveform support. Adjustable from <4% to >12%
• Efficient unbalanced power transmissions
• Low EVM waveform support. Adjustable from <4% to >12%
• Efficient unbalanced power transmissions
Additional features:
• Hardware ready to support 1 LTE carrier with 1.4MHz, 3MHz, 5MHz and 10MHz bandwidth or up to 3 LTE carriers
with 15MHz maximum bandwidth.
• Low receiver noise figure (2dB), enables the base station OEM to reach excellent receiver sensitivity. Two Rx chains
support receive diversity, increasing uplink performance even further.
• Two externally pluggable SFP sockets enabling field selectable optical interfaces including 1310nm(UL)/ 1550nm(DL)
single-mode single fiber and 850nm multi-mode dual fiber. Electrical interfaces are supported as well
• Software supports Ethernet over CPRI and allows easy implementation of customer specific requirements.
• Supports 2-way MIMO. Two units can be combined to support 4x4 MIMO or 2-way MIMO with 4 receive branches.
• Supports 2-way MIMO. Two units can be combined to support 4x4 MIMO or 2-way MIMO with 4 receive branches.
•
External AISG interface, I2C interface and a serial port for additional system control and monitoring.
• Extensive Operations and Maintenance functionality supported through flexible O&M SW. Self-diagnosis and alarms
continuously monitoring:
• High MTBF (>375,000 hours)
