　　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
