In-Line Amplifier Powered by the Receiver

If the RF equipment draws a total of less than 200 mA, the antenna LNA and in-line amplifier both accept a +5.0 VDC supply, and the inline amplifier is capable of passing the DC power from the receiver, then the equipment can be connected directly to the receiver without the need for an external power supply. Figure: In-Line Amplifier Powered by the Receiver illustrates this configuration.

1

Most GNSS antenna LNAs safely operate with +5.0 VDC input voltage.

2

The in-line amplifier is powered by the +5.0 VDC provided by the receiver. The in-line amplifier is shunt-fed, which allows the DC power to continue to the antenna.
