It features a patch element with 40% wider bandwidth than hitherto available in this format. Unlike its competitors, both GPS-L1 and GLONASS signals are included in the 1dB received power bandwidth. The TW3320/TW3322 has a two stage Low Noise Amplifier with a mid-section SAW. An optional tight pre-filter is available with part number TW3322 to protect against saturation by high level sub-harmonics and L-Band signals. TW3320/TW3322 Shown with Low Profile Radome. Conical Radome also available The TW3320/3322 is housed in a permanent mount industrial-grade weather-proof enclosure. Two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0) ## **Applications** - Cost Sensitive Mission Critical Positioning - Military & Security - Fleet Management & Asset Tracking ## **Features** - Low noise LNA: 1 dB typical (TW3320) - High rejection mid-section SAW filter - Available Pre-filter (TW3322) - High gain: 28 dB typ. - Wide voltage input range: 2.5 to 16 VDC - IP67 weather proof housing - Low Power: 9mA typ. ## **Benefits** - Bandwidth fully Includes GPS-L1 & GLONASS - Excellent multipath rejection - Increased system accuracy - Excellent signal to noise ratio - Great out of band signal rejection - Ideal for harsh environments - RoHS compliant ## TW3320/TW3322 Wideband GPS/GLONASS Antenna ## **Specifications** ## **Antenna** Architecture 1 dB Bandwidth 10dB Return Loss Bandwidth Antenna Gain (with 100mm ground plane) Axial Ratio Wideband Single Feed Patch 31 MHz 45MHz 4.5 dBic <4dB @ 1590MHz, 8 dB typical at band edges ## **Electrical** Architecture TW3320 LNA stage 1 -> SAW filter-> LNA stage 2 TW3322 SAW Prefilter ->LNA stage 1 -> SAW filter-> LNA stage 2 Filtered LNA Frequency Bandwidth 1574 to 1606 MHz Polarization RHCP Gain (1575.42 to 1606 MHz) 28dB min., TW3320; 26dB, TW3322, Gain flatness +/- 2 dB, 1575 to 1606 MHz Out-of-Band Rejection <1500 MHz >35 dB <1550 MHz >25 dB >1640 MHz >35 dB VSWR (at LNA output) <1.5:1 Noise Figure 1 dB typ., TW3320; 2.5dB typ., TW3322 Supply Voltage Range (over coaxial cable) +2.5 to 16 VDC nominal Supply Current 9 mA typ ESD Circuit Protection 15 KV air discharge ## **Mechanicals & Environmental** Mechanical Size 66.5 mm dia. x 21 mm H Operating Temperature Range 40 to +85 °C Enclosure Radome: EXL9330, Base: Zamak White Metal Weight 150 g Environmental IP67 and RoHS compliant Shock Vertical axis: 50 G, other axes: 30 G Vibration 3 axis, sweep = 15 min, 10 to 200 Hz sweep: 3 G ## **Ordering Information** Legacy Part Numbers: TW3320 – GPS/Glonass Antenna TW3320 – GPS/Glonass Antenna 32-3320-xx-yy TW3322 – GPS/Glonass Antenna with Pre-filter 32-3322-xx-yy Connector: xx = 00 TNC xx = 01 N Type (premium applies) Radome Colour yy = 10 Dark grey low profile yy = 11 White low profile * As a result of a growing product portfolio, Tallysman has rationalized its part number system.
