Hybrid Coupler Specifications

Insertion Loss
Insertion loss is the difference in power between the input signal and the output signal above the theoretical split loss of 3.0 dB. It is the level of attenuation of a signal injected into an output port as seen at the other output port with the input terminated in 50 ohms.

Amplitude Balance 
The maximum difference in the power level between the output signals.

Phase Balance
The maximum phase difference in degrees between the output signals.

Isolation
The isolation is used to define the amount of output vport to port crosstalk.

VSWR
The VSWR (Voltage Standing Wave Ratio) at any given port (with all other ports terminated) defines the degree of mismatch between the input signal and the input port and thus is a measure of the loss of input signal at that port.
