Formula:

The power split in an N-way power divider can be approximated by the following formula for equal splitting:

P_out=P_in/N

Where:

• Pout​: Power at each output port (in watts or dBm)
• Pin​: Total input power (in watts or dBm)
• N: Number of output ports (N-way)

The insertion loss in an ideal N-way power divider can be estimated using:

L_insertion=10log_⁡10N

Where:

• L_insertion: Insertion loss (in dB)
• NNN: Number of output ports

This formula assumes ideal conditions with no additional losses, which helps you get an approximate understanding of how power is distributed.
