It is especially designed for precision industrial, agricultural and military OEM applications and offers excellent circular polarized signal reception, multipath rejection and out of band signal ejection. The TW2405 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. TW2405 Dimensions (mm) The TW2405 comes in a compact circular form factor with a built-in 50 mm diameter ground plane, and a 15 cm RG174 cable. ## **Applications** - High Accuracy & Mission Critical GPS - Precision Agriculture, Mining & Construction - Military & Security - Avionics - - Law Enforcement & Public Safety - Fleet Management & Asset Tracking ## **Features** - Great axial ratio: <3 dB over full bandwidth - Low noise LNA: 1 dB - High rejection SAW filter - High gain: 28 dB typ. - Low current: 10 mA typ. - ESD circuit protection: 15 KV ## **Benefits** - Excellent multipath rejection - Increased system accuracy - Excellent signal reception - Great out of band signal rejection - Compact form factor - RoHS compliant - Wide voltage input range: 3.0 to 10 VDC Wireless TW2405 Embedded GPS/GLONASS Antenna **Specifications** Vcc = 3V, over full bandwidth, T=25°C **Antenna** Architecture Dual, Quadrature Feeds 1 dB Bandwidth 30 MHz Antenna Gain (with 100mm ground plane) 4.25 dBic Axial Ratio over Bandwidth (over full bandwidth) ≤3 dB **Electrical** Architecture One LNA per feed line, mid section SAW filter Filtered LNA Frequency Bandwidth 1574 to 1606 MHz Polarization RHCP Gain 28 dB min., 1575.42 to 1606 MHz Gain flatness +/- 2 dB, 1575 to 1605 MHz Out-of-Band Rejection <1500 MHz >32 dB <1550 MHz >25 dB >1640 MHz >35 dB VSWR (at LNA output) <1.5:1 Noise Figure 1 dB typ.
