  描述:

  The LNFA1X4 Low Noise Filtered Amplified GPS Splitter is a one input,

  four outpu device with 0dB nominal gain. The device features a low

  noise input section establish an overall system noise figure.

  Excellent port-to-port isolation and unity gain are achieved by padded outputs.

  The device features excellent frequency selectivity around the L1 band to

  prevent interference from other high power radio frequency sources,

  such as cellular tranmitter station. The LNFA1X4 device will power

  itself and an external GPS antenna from a 5.0 VDC source connected

  on any of the RF Outputs. A “hunt-and-pick” circuit is used to select

  only one DC input for power in the event that more than one source is

  connected. Remaining DC inputs are switched to a 200Ω resistor to simulate

  antenna current draw
