|Quadrature Hybrids - 90° and 180°|
Hybrid Application and Definitions
By definition, a hybrid is a four-port directional coupler with a -3dB coupling coefficient. It is theoretically matched at all four ports and has two ports where pair members are isolated from each other.
IsolationThe difference in dB of the signal level measured between output ports with the input port properly terminated.
VSWRVoltage Standing Wave Ratio is a measure of the deviation of impedance from the characteristic impedance of the power divider.
Phase BalanceThe maximum peak-to-peak difference in phase (in degrees) between the outports of the power divider over the specified frequency range.
Input PowerThe maximum power that may be supplied to the input port with all outports properly terminated.
Insertion LossThe net unrecoverable power loss in dB based on one way transmission through the power divider.
