TW125 Low Current / Low Voltage 1.2 to 1.8 GHz 28 dB gain In-line Amplifier Th e TW125 is a low cost, rugged, w aterproof, low noise, low current/low voltage, 1.2 to 1.8 GHz band, 28dB 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 mast-mount, 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 F eatures Benefits Low Current / low voltage Improves signal reception Very low noise Enables extended cable runs Wide input voltage 3 to 16 Volts Avoid installation of costly low- loss cable Nickel-plated brass, IP67 compliant housing Powered via antenna coax from receiver Fits in line with antenna cable No external DC power supply 50 Ohm port impedance required Available SMA, TNC, and N-Type jack Easy to install - mounting clamp connectors included RoHS and REACH compliant TW125 Low Current / Low Voltage 1.2 to 1.8 GHz 28 dB gain In-line Amplifier Specifications Vcc =3.3V, over full bandwidth, T=25 C Electrical Nominal Gain 28 dB +.1/-.2 dB typ.
