RF Circuits

Here is a device called a power splitter (divider/combiner). You can use this to phase four antennas together for increased gain or combine the input/outputs of amplifier for increased power.

This 4 to 1 (4-1=4 ports) power splitter work at 2.4GHz. You will use it for stack 4 pieces of 2.4 GHz helical antenna for get 6 dB more gain on AO-40 satellite down link receive.
