Canadian-based Tallysman is releasing a new wideband 28-dB inline amplifier, covering the full GNSS spectrum from 1 to 2 GHz.

The TW125B is a low-cost, rugged, waterproof, low-noise, low-current/low-voltage, 1-to-2-GHz band, inline amplifier. It is specially designed to amplify all GNSS frequency signals, from GPS L5 (1164 MHz) to GLONASS G1 (1610 MHz) and beyond. 

The new TW125B provides for long cable runs from antenna to receiver, for applications such as mast-mount, large vehicle and timing systems, without degradation of system sensitivity.

Its low loading allows for both the antenna and the TW125B in-line amplifier to be powered by the GNSS receiver. The amplifier adds just 12mA of load on the circuit, well within the capabilities of most GNSS receivers on the market. The TW125B passes DC supply to the antenna, therefore not requiring additional hardware such as bias-T, power cable and power supply. 

The amplifier is available with TNC, N-Type, or SMA connectors, and it is REACH- and ROHS-compliant.
