3997D-HR

MOBILE ANTENNAS GPS Antennas 3997D-HR 3997D-HR Low Profile, High Rejection Surface Mount GPS Antenna RoHS COMPLIANT The 3997D-HR surface mount GPS Antenna provides high performance and high out-ofband rejection in a very small form factor. It features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects. This element, along with a low noise amplifier and 2 dual SAW filters, enables the 3997D-HR to provide a consistent, clear signal while minimizing loss-of-lock when GPS conditions are less than ideal. The 3997D-HR is housed in a very compact all-plastic, non-corrosive low profile package. The 3997D-HR is ideal for permanent installations in asset tracking and timing syncronization where performance and size are critical factors. 3997D-HR Features • • • • • Weather proof, non-corrosive, GE Lexan EXL9330 enclosure Extremely low in-vehicle connector profile Voltage range: 2.7 to 5.5 V ESD Protection: >15 kV High out-of-band signal rejection STANDARD CONFIGURATION Model Connector Mount 3997D-HR MCX Jack 4 x 4-40 screw mounting holes ELECTRICAL SPECIFICATIONS - GPS ANTENNA Frequency Band Nominal Gain Polarization Current Draw 1575.42 MHz ± 10 MHz 3 dBic @ 90° -2 dBic @ 20° Right Hand Circular 22 mA @ 5V ELECTRICAL SPECIFICATIONS - GPS ANTENNA, continued Out of Band Rejection Amplifier Gain Nominal Impedance Noise Figure DC Voltage VSWR ≥ 55dB @ 1559MHz ≥ 60dB @ 1625MHz 28dB +/- 3dB 50 ohm 3.9 dB (typical) 2.7-5.5 VDC (Internally Regulated) < 1.9:1 MECHANICAL & ENVIRONMENTAL SPECIFICATIONS Dimensions Weight Shock Vibration 1.7” x .53” (44.28 x 13.42 mm) .057 lbs (26 g) Vertical axis 50G, other axes 30G 3 axis, sweep = 15 min 10 – 200 Hz log sweep: 3G PCTEL, Inc.
