90° Hybrids split an input signal into two equal amplitude output signals which are 90° out of phase from each other. Like in-phase dividers, 90° Hybrids may also be used as a power combiner.

Insertion loss is the difference in power between the input signal and the output signal above the theoretical split loss of 3.0 dB.
The maximum difference in the power level between the output signals.
The maximum phase difference in degrees between the output signals.
The isolation is used to define the amount of output port to port crosstalk. 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.
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.
