TW120 25 dB GPS L1 In-line Amplifier T he TW120 by Tallysman Wireless is a rugged waterproof, low cost, low noise, low power, narrow band 25dB gain in- line amplifier, specially designed to tightly filter and boost weak GPS L1 signals, while maintaining low antenna noise figures. The TW120 provides for much longer cable runs from antenna to receiver, for applications such as mast- mount, roof-top and large vehicle installations, without any degradation of TW120 Dimensions (mm) system sensitivity. The TW120 passes DC directly from input to output to support centre conductor DC supply to the antenna, and so avoiding the need for an additional bias source or bias T. Applications GNSS and Telematics Systems Wireless Telecom & Cellular Base Station Timing Applications Commercial and Industrial Timing and Synchronization Applications Features Benefits Very low noise Improves signal reception Wide input voltage range, 3 to 10 VDC Enables extended cable runs Powered via antenna coax from receiver Avoid installation of costly low-loss cable 50 Ohm port impedance Fits in-line with antenna cable Cylindrical nickel-plated brass, IP67 No external voltage supply needed compliant housing Maintains low antenna LNA noise figure Gold-plated SMA & TNC Jack connectors Easy to install mounting clamp included RoHS compliant TW120 25 dB GPS L1 In-line Amplifier Specifications Vcc =3.3V, over full bandwidth, T=25 C Electrical Gain 25dB +3dB/-0dB typ.
