The TW3040/TW3042 features a custom high performance, wide band patch element, a 40dB gain LNA stage and a high rejection out-of-band SAW filter. The TW3042 is equipped with a sharp SAW pre-filter to provide strong protection from out-of-band signals. It provides ±10MHz bandwidth centred on 1575.42 MHz and covers the GPS L1, Galileo E1 and SBAS (WAAS/EGNOS/MSAS) signals, and it provides great axial ratio, excellent circular polarized signal reception, great multipath rejection and great out-of-band signal rejection. The TW3040/TW3042 is housed in a permanent mount industrial-grade weather-proof enclosure and two options for pole mounting are available an L- bracket (P/N#23-0040-0) or a pipe mount (P/N#230065-0). TW3040/TW3042 Dimensions (mm) Flat Radome shown. Conical Radome also available ## **Applications** - Mission Critical GPS Tracking & Timing - Precision Agriculture, Mining & Construction - Military & Security - Avionics - Law Enforcement & Public Safety - Fleet Management & Asset Tracking ## **Features** - Great axial ratio - Low noise LNA: 1 dB - High rejection SAW filter - High gain: 40 dB typ. - Low current: 15 mA typ. - ESD circuit protection: 15 KV ## **Benefits** - Excellent multipath rejection - Increase system accuracy - Excellent signal to noise ratio - Great out of band signal rejection - Ideal for harsh environments - RoHS and REACH compliant - Wide voltage input range: +2.5 to 16 VDC - Weather proof housing: IP67 ## TW3040/TW3042 Permanent Mount GPS L1 Antenna **Specifications** Vcc = 3V, over full bandwidth, T=25°C ## **Antenna** Antenna Architecture Antenna Element Gain (100mm ground plane) Axial Ratio (over full bandwidth) Single-feed RHCP ceramic patch 4 dBic at 90° 4 dB at 90° ## **Electrical** Architecture 3 stage LNA circuit + a mid section SAW filter.
