Wi-Sys Communications Inc. WS1357 13 mm x 13 mm x 5.8 mm Ultra Compact Embedded GPS Antenna Series Applications: GPS Enabled Mobile Phones, PDAs & Laptops Portable GPS Handhelds GPS enabled M2M Military and Law Enforcement Radios GPS Enabled Offender Monitoring Systems Asset Tracking Equipment Automotive & Marine Navigation Systems The Ultra Compact WS1357 Embedded GPS antenna series is most ideal for GPS Enabled mobile phones, PDAs, laptops and portable GPS Handhelds. The WS1357 antenna series features a 13 mm x 13 mm x 4 mm ceramic patch element, ESD circuit protection, a low noise amplifier and a SAW filter, enabling the WS1357 series to provide great out-of-band signal rejection performance, consistent and clear signal while minimizing loss-of-lock in an extremely small form factor. With its very compact 16 mm x 16 mm x 5.8 mm dimensions, the WS1357 antenna series is perfectly suited for OEM applications. WS1357 dimensions Features: 2.7 to 5 V operation Available with built-in 30mm ground plane (WS1367) Low power 18dB design also available (WS1356) Optional cable types and lengths available Other connector types available Ideal for embedded applications Low price Technical Specifications Wi-Sys Communications Environmental Specifications WS1357 Ultra Compact Operating temp: -40c to +85c (-45c to +80c storage) Humidity: 95% max (non condensing) Embedded GPS Antenna Mechanical Designed for easy integration into OEM WS1357 16 mm x 16 mm x 5.8 mm handheld platforms, the WS1357 antenna Shock: Vertical axis 50G, other axes 30G integrates a highly robust ESD protection Vibration: 3 axis, sweep = 15 min circuit, a low-noise amplifier to ensure a reliable 10200 Hz log sweep: 3G and clear signal for the GPS receiver even in Antenna Response difficult conditions, as well as a SAW filter for Frequency: 1575.42 MHz even greater performance for hand held Gain: 0.5 dBic telematics applications where out-of-band signal Polarization: Right Hand Circular rejection is required. The PCB protrudes 1.5mm Axial ratio: 90 4 dB, 20 6 dB Electrical Ordering Information: Voltage: 2.7 5 VDC Current: 9 mA 3.3V, 15 mA 5V, WS1357-A - Designed to operate with just its 16mm LNA Connector: H.FL, other connector types available PCB (embedded ground plane) with no other ground plane. Cable: 1.5 mm dia. CO-6F.FH-SB cable It is tuned on frequency with this small ground plane, Cable length: 15 cm (6), other lengths available which, precisely because it is small, is also the minimum gain configuration.
