Product description: GNSS Antenna Splitter - GNSS antenna splitter with DC pass - SparkFun SPX-21223

GNSS Antenna Splitter is a 50-ohm antenna splitter that allows you to connect a single GNSS antenna to two boards or modules. Splits the antenna signal from Port S equally between Port 1 and Port 2.

The GNSS Antenna Splitter is an experimental product from the SparX series. These are advanced solutions that do not go into regular production. They are produced in very small quantities. They are tested by SparkFun, but do not have its technical support. Visit the forum for help or to ask a question.

50-ohm antenna splitter for connecting a single GNSS antenna to two boards or modules.

Principle of operation

By default, the splitter feeds DC from Port 1 to the antenna (Port S), so you can power an active antenna. It is also possible to configure:

  • By opening jumper 1 and closing jumper 2, you can provide DC power from Port 2.
  • When jumper 1 is open, DC power can also be provided from the built-in Qwiic connector.
  • When jumper 1 is open and the Qwiic connector and VCC port are disconnected, you can use our board as a passive 50:50 signal splitter or combiner.

In our offer you will also find the NEO-D9S correction data receiver - check it out!
