TW164B

The Calian TW164B is a top-tier signal splitter designed to connect one antenna to up to four receivers. It supports a wide range of GNSS bands, including GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, BeiDou-B1/B2/B2a/B3, Galileo-E1/E5a/E5b/E6, NavIC-L5, and L-Band correction services. This model features four in-line receiver ports on the backside and an antenna port on the frontside.

Key Features

• High Availability: GNSS is crucial for safety, security, timing, and infrastructure applications, all requiring high availability. The TW164B ensures resilient, fault-tolerant performance to prevent service interruptions.
• Smart Power Management: Unlike first-generation splitters, which had a single point of failure, the TW164B accepts power from all attached receivers. It prioritizes power from Port #1 if within the 3.3 - 12.5 VDC range. If Port #1 fails or its power is out of range, the splitter switches to the next port in numerical order, ensuring continuous operation.
• Antenna Fault Detection: If the antenna fails and does not draw current, the TW164B signals an antenna fault by providing all connectors with a current draw lower than 1 mA.

Performance and Design

• Best-in-Class Performance: The TW164B excels in noise figure, isolation, and linearity.
• Robust Construction: Housed in a compact, lightweight, waterproof (IP67) aluminum casing, it is corrosion-protected and built to last.
• Connector Options: Available with TNC or type-N connectors, it offers standard gain to compensate for signal-splitting loss.

Recommendations

Unused Ports: It is recommended to terminate unused ports with a 50 Ohm load.
