The LNFA1X4 from GPS Networking is a 4-Way Low-Noise Filtered Amplifier (LNAF) Power Divider that operates from 1.1 to 1.7 GHz. It provides a gain of 0 dB, has a noise figure of 4.75 dB (L1 band), and provides isolation of more than 61 dB between ports. This power divider has an amplitude balance of less than 1 dB and a phase balance of 6°. It uses padded outputs to provide excellent port-to-port isolation and unity gain. This divider has high-frequency selectivity around the L1 band to prevent interference from other high-power radio frequency signals. It requires a DC supply of 5.0 V and consumes 7 mA of current. An additional “pick-and-choose” circuit is integrated to select only one DC input when more than one source is connected.
The LNFA1X4 is available in a module that measures 6.75 x 2.50 inches with options for N-type, SMA, TNC, and BNC (all female) connectors and is ideal for cell sites, splitting, and amplifying roof antenna between 4 GPS/GLONASS/GNSS receivers and large-signal distribution network applications.
