They are especially designed for timing, mobile, precision and military applications. They provide truly circular response over the antenna’s entire bandwidth thereby producing superior multipath signal rejection. The TW3440/TW3442 each feature a highly circular dual-feed wideband patch element, with a three stage Low Noise Amplifier. This configuration provides excellent axial ratio that is constant across the full frequency band. An optional tight pre-filter is available with part number TW3442 to protect against saturation by high level sub-harmonics and L-Band signals. The TW3440/TW3442 is housed in a permanent mount industrial-grade weatherproof enclosure, and is available with a wide variety of connectors. ## **Applications** Shown with low profile radome, conical radome also available - GPS / GLONASS Long cable Mobile/fixed Installations - High Accuracy & Mission Critical Global Positioning - Precision Agriculture, Mining & Construction - Military & Security - Avionics - Law Enforcement & Public Safety - Fleet Management & Asset Tracking ## **Features** - Great axial ratio: 1 dB typ. - High gain LNA: 40 dB min. - Low noise LNA: 1dB/3.5dB typ TW3440/TW3442 - Available sharp pre-filter (TW3442) - Low current: 19 mA typ. - Wide supply voltage: 2.5 to 16 VDC - IP67 weather proof housing - Available conical radome (Timing Apps) ## **Benefits** - Excellent circular polarisation - Long Cable Runs - Excellent signal to noise ratio - Excellent multipath rejection - Exceptional out-of-band rejection (TW3442) - Increased system accuracy - Ideal for harsh environments - RoHS compliant ## TW3440/TW3442 GPS/GLONASS Timing Antenna **Specifications** Vcc = 3V, over full bandwidth, T=25°C ## **Antenna** Architecture 1 dB Bandwidth Antenna Gain (with 100mm ground plane) Axial Ratio (over full bandwidth) Dual, Quadrature Feeds 32 MHz 4.25 dBic 1 dB typ., 3 dB max. ## **Electrical** Architecture TW3440: One LNA per feed ->Combiner ->SAW -> 2-Stage LNA TW3442: (SAW-> LNA) per feed ->Combiner -> SAW -> 2 Stage LNA, Filtered LNA Frequency Bandwidth 1574 to 1606 MHz Polarization RHCP LNA Gain 40 dB min., 1575.42 to 1606 MHz Gain flatness +/- 2 dB, 1575 to 1606 MHz Out-of-Band Rejection <1500 MHz >32 dB (TW3440) >50dB (TW3442) <1550 MHz >25 dB >50dB >1640 MHz >35 dB >70dB VSWR (at LNA output) <1.5:1 Noise Figure 1 dB typ.
