Introduction
This document outlines the hardware integration for the D17XX IP Mesh baseband transceiver card.
The Cobham D17XX PCB is a digital diversity IP Mesh transceiver, designed specifically as the
baseband and IP processing card for the Cobham IP Mesh phase 4 system. The system allows
wireless IP, digital video and audio transmission in mobile, urban and non-line-of-sight scenarios.
Equipped with Ethernet and serial control interfaces, the D17XX is easy to integrate into a larger
system.
The key design criteria for this solution were:
Low power consumption
Small size
Ease of integration
Features include:
2.5MHz / 3MHz / 3.5MHz / 5MHz and 6MHz operating bandwidth modes
Two-way diversity Maximum Ratio Combining for fade and multipath elimination
Internal AES 128 / 256bit encryption (optional)
Twin IP interfaces
Multiple Serial interfaces
SMP connectors for reduced size and ease of connection
Optional Encoder offering very low delay video operation for real time applications
Interfaces for optional 1W amplifier
Talk-back Audio
Micro SD card for 32GB storage
Low power—typically ?W
