TW125 Low Current / Low Voltage 1.2 to 1.8 GHz 25 dB gain In-line Amplifier The TW125 by Tallysman Wireless is a low cost, rugged, waterproof, low noise, low current/low voltage, 1.2 to 1.8 GHz band, 25dB gain in-line amplifier, specially designed to amplify all GNSS frequency signals, from GPS L2 to GLONASS L1. The TW125 provides for much longer cable runs from antenna to receiver, for applications such as mastmount, large vehicle and timing systems, without degradation of system sensitivity. TW125 Dimensions (mm) Its low loading allows for both the antenna and the TW125 in-line amplifier to be powered by the GNSS receiver. The TW125 passes DC supply to the antenna, therefore not requiring additional hardware such as bias-T, power cable and power supply. Applications  All GNSS Signals – GPS, GLONASS, Galileo & SBAS  Commercial, Industrial and Military Telematics Systems  Wireless and Telecom Timing and Synchronization Applications Features Benefits            Low Current / low voltage Very low noise Wide input voltage 3 to 10 Volts Nickel-plated brass, IP67 compliant housing Powered via antenna coax from receiver 50 Ohm port impedance Available SMA & TNC jack connectors RoHS compliant    Improves signal reception Enables extended cable runs Avoid installation of costly lowloss cable Fits in line with antenna cable No external DC power supply required Easy to install - mounting clamp included TW125 Low Current / Low Voltage 1.2 to 1.8 GHz 25 dB gain In-line Amplifier Specifications Vcc =3.3V, over full bandwidth, T=25 °C Electrical             Nominal Gain Pass Band Ripple Impedance Noise Figure Bandwidth Input VSWR Output VSWR Reverse Isolation Output 1dB Output IP3 Supply Range voltage Supply Current 25 dB +4/-0 dB typ. +/-2 dB 50 Ohms 1.5 dB max. 1.2 to 1.8 GHz 1.5 typ. / 2 max. 1.5 typ. / 2 max. >35 dB -10 dB +5 dBm 3 to 10 VDC Nominal 25 mA typ.
