GNSS module U50

Introduction
The U50 datalink module is an RX/TX data-link module covering the full 410–470 MHz band. Its surface-mounted (SMT) form factor and compact dimensions are intended for easy integration into GNSS-related and other embedded radio applications.

Key Features

• Adjustable frequency range: 410–470 MHz
• Operates as TX / RX and repeater (half-duplex)
• User-selectable output power: 0.5 W, 1 W, 2 W
• Surface-mounted design (SMT) and compact footprint for integration
• Channel spacing: 12.5 kHz
• Air baud rates: 9600 and 19200 bps selectable
• Supports common UHF datalink protocols

Product Highlights

• TX / RX / Repeater: Full 410–470 MHz coverage with 12.5 kHz channel spacing, designed for GNSS and telemetry links
• Compact SMT Package: Small footprint (40 × 30 × 3 mm including connector) and low power draw to simplify board-level integration
• Protocol Compatibility: Supports Transparent, South, Mac and TT450S protocols for interoperability with industry devices
