TW162
TW162 1-to-2 Port Smart Power GNSS Signal Splitter
Frequency Coverage: Full GNSS Spectrum

Overview
The Tallysman TW162 is a professional-grade full GNSS band signal splitter that connects
one antenna to two receivers, and supports GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASSG1/G2/G3, BeiDou-B1/B2/B2a/B3, Galileo-E1/E5a/E5b/E6, NavIC-L5, and L-Band correction
services.
GNSS has become a critical component in safety, security, timing, and infrastructure
applications, all of which require very high availability. As a result, resilient fault-tolerant
components are essential to avoid service interruptions.
The design of first-generation GNSS signal splitters suffered from a single point of failure: onlyone attached receiver powered the splitter and the antenna. If this receiver failed or was
unplugged, all attached receivers also failed.
Tallysman’s current-generation TW162 Smart Power GNSS signal splitter provides two
additional key features:First, it accepts power from all attached GNSS receivers and selects power from a receiverusing the following protocol. Port #1 is given priority if its voltage is within the specified range(3.0 - 12.5 VDC). However, if port #1’s receiver is disconnected or if its receiver power goes
below the under-voltage or above the over-voltage specification, the TW162 will switch to thenext port in numerical order, as long as its power and voltage are within the expected range.
The switching and port selection is, therefore, deterministic.
Second, if the antenna fails and does not draw current, the TW162 will provide all connectors
with a current draw lower than 1 mA, indicating an antenna fault.
The TW162 offers the best in-class performance in terms of noise figure, isolation, andlinearity. In addition, it is packaged in a robust, compact, lightweight, and water-proof (IP67)
corrosion-protected aluminum housing.
The TW162 is available with either TNC or type-N connectors and offers standard gain tocompensate for signal-splitting loss.
