    LNA-3000-S581 Low Noise Amplifier Description

    Simplex, Half-Duplex, DAMA and IW signals (TDD) compatible Smart Booster for UHF applications. It substantially improves UHF Satcom downlink signals by an effective 7-15 dB, depending on the transceiver or radio used. It will also enhance LOS (Line of Sight) Simplex and Half-Duplex communications by the same factor above. Custom versions available covering other frequency ranges.  

    Key features of this LNA

    • Small and Lightweight (3.5" x 3.5" x 2" or 9 cm x 9 cm x 5 cm)
    • One button and automatic-ON operation
    • Self-powered (a 4 hour charge will typically support continuous operation for up to 10 days)
    • Auto Two-mode internal charger (RF Quiet/Voltage tolerant) supports charging from 5-16 V sources, observes USB-2 charging limits when powered from a standard USB port
    • Built-in solar cell extends operation lifetime
    • Compatible with the following accessories:
      • Suction Cup Mount (ACC-0002), to attach to non-metal and metal, smooth surfaces
      • Magnetic/Mag Mount (ACC-0003-581 or ACC-0001-581), to attach to ferrous metal surfaces
      • Bolt-on, AV 2090, 4 hole pattern compatible, direct Vehicle Mount (ACC-0008)
      • Standard Camera Tripod
      • Make your own bracket - all you need is a 1/4" (6.4 mm) hole
    • May be transported on passenger aircraft, or shipped via common carrier without any special UN markings
    • Waterproof to 3 m (6 ft) when connectors are sealed

    LNA-3000-S581 Technical Specifications

    • Operating Frequencies: 243-320 MHz (Active/Bypass), 360-380 MHz (Bypass only)
    • Maximum RF Power: 25 Watts
    • Gain:
      • Bypass or Passive mode: better than -2 dB
      • Active mode: better than +15 dB
    • Noise Figure: 2 dB typical
    • Nominal Impedance (Radio/Red Connector): 50 Ohms (RF), open circuit (DC) (internally DC protected to 16 VDC)
    • Maximum VSWR: <1.5
    • Connector Interfaces: SMA, female (Red to Radio/Transceiver, Green to Antenna)
    • DC Power requirements: LNA is powered from its internal, redundant rechargeable batteries, for up to 10 days on a single 4 hour charge
    • Battery Charging Interface: Radio/Transceiver (Red) SMA connector
    • Battery Charging Modes:
      • RF Quiet mode: 5.0-6.5 VDC @ 400 mA nominal. In this mode, the LNA may be used without additional charger noise. If LNA is powered continuously through a Bias-Tee, this is the preferred charge mode.
      • Wide Voltage mode: 6.5-16 VDC @ <400 mA (voltage dependent, lower current at higher voltages). This mode enables LNA to be charged from many possible sources of power.
    • Operating Temperature: -40°C to +85°C (-40°F to +185°F)
    • Dimensions: 9 cm x 9 cm x 5 cm (3.5 in x 3.5 in x 2 in)
    • Weight: 300 g (0.60 lbs)
