It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. It is especially suitable for high accuracy applications, and also offers high out of band signal rejection. The TW3710 features a dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage. This configuration provides excellent axial ratio that is constant across the full frequency band along with a superb phase linear response and tight phase centre variation providing performance normally associated with much higher priced antennas. TW3710 / TW3712 Dimensions (mm) The TW3710 is housed in a through-hole mount, weather-proof enclosure for permanent installations. L Bracket or Pipe Mount adapters (part numbers 23-00400, 23-0065-0 respectively) are available for non-rooftop installation. A 100mm ground plane is recommended for non-roof-top installations. ## **Applications** - High Accuracy & Mission Critical Global Positioning - Precision Agriculture, Mining & Construction - Military & Security - Avionics - Law Enforcement & Public Safety - Fleet Management & Asset Tracking ## **Features** - Covers all GNSS Frequencies - Great axial ratio: 1 dB typ. - Low noise LNA: 1 dB - High rejection SAW filter - High gain LNA: 28 dB typ. - Low current: 15 mA typ. - Wide voltage input range: 2.5 to 16 VDC ## **Benefits** - Excellent circular polarisation - Excellent multipath rejection - Excellent signal to noise ratio - Great out of band signal rejection - Increased system accuracy - Ideal for harsh environments - RoHS and REACH compliant ## TW3710 Multi-Constellation Antenna **Specifications** At; Vcc = 3V, over full bandwidth, T=25°C ## **Antenna** Architecture 2 dB Bandwidth Antenna Gain (with 100mm ground plane) Axial Ratio (over full bandwidth) horizon to horizon Dual, Quadrature Feeds 49 MHz 4.75 dBic <1.5 dB typ., <2.5 dB max. ## **Electrical** Filtered LNA Frequency Bandwidth Polarization LNA Gain Gain flatness Out-of-Band Rejection <1500 MHz <1540 MHz >1640 MHz VSWR (at LNA output) Noise Figure Supply Voltage Range (over coaxial cable) Supply Current ESD Circuit Protection 1557 to 1606 MHz RHCP 28 dB min. +/- 2 dB, 1557 to 1606 MHz >40 dB >20 dB >45 dB <1.5:1 1 dB typ. 2.5 to 16 VDC nominal (12VDC recommended maximum) 15 mA typ, 20mA max. at 85°C. 15 KV air discharge ## **Mechanicals & Environmental** Mechanical Size 66.5 mm dia. x 21 mm H Operating Temp.
