The TW1010/TW1012 features a precisely tuned single feed ceramic patch element. It has a two stage Low Noise Amplifier (LNA) with a mid-section SAW. An optional tight pre-filter is available with part number TW1012 to protect against saturation by high level sub-harmonics and L-Band signals. ## TW1010/TW1012 Dimensions with RG174 cable (mm) The TW1010/TW1012 covers the GPS L1 and SBAS (WAAS /EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers great circular polarized signal reception, multipath rejection and out of band signal rejection. The TW1010/TW1012 has a built-in 35mm circular ground plane that can be augmented with host system ground surfaces. Patch Elements are susceptible to detuning by the local environment. Tallysman offers custom services to assist with integration of OEM modules into an end user solution. Custom cable lengths and connectors are available. ## **Applications** - High Accuracy & Mission Critical GPS - Precision Agriculture, Mining & Construction - Military & Security - Avionics - Law Enforcement & Public Safety - Fleet Management & Asset Tracking ## **Features** - Very low noise LNA: 1 dB (TW1010). - Great axial ratio: <4dB at Zenith - High rejection SAW filter - LNA gain: 28 dB typ (TW1010). - Low current: 9 mA typ. - ESD circuit protection: 15 KV - Wide Supply voltage: fixed 2.5V to 16V ## **Benefits** - Low Profile: 7.25mm - Great multipath rejection - Increase system accuracy - Excellent signal to noise ratio - Great out of band signal rejection - Compact form factor - RoHS compliant ## TW1010/TW1012 Embedded GPS L1 Antenna **Specifications** At; Vcc = 3V, over full bandwidth, T=25°C ## **Antenna** Architecture Polarization Antenna Gain (70mm ground plane) Axial Ratio Frequency/Bandwidth (-10dB Return Loss) Custom single-feed ceramic patch RHCP 4 dBic at 90° 4 dB at 90°, 6dB at 20° 1575.42MHz +/- 10MHz ## **Electrical** Architecture TW1010 TW1012 Gain (1575.42 to 1606 MHz) Filtered LNA Frequency Bandwidth (3dB) Out-of-Band Rejection VSWR (at LNA output) Noise Figure Supply Voltage Range (over coaxial cable) Supply Current ESD Circuit protection LNA stage 1 -> SAW filter-> LNA stage 2 SAW Prefilter ->LNA stage 1 -> SAW filter-> LNA stage 2 26dB min., TW1010; 24dB min, TW1012, 1575.42MHz +/- 10MHz TW1010: <1500MHz >35dB.
