There are many things related to system, amplitude, transmission parameters, return loss measurements, balanced circuits, and measurements are explained inside the report. In this report we can get info related to error, measurement techniques, performance, equation, and phase.
The report presents information about impedances, parameters, loss measurements, balun, and amplitude error. These are selected from the report:
Measurements techniques for baluns A balun consists of an “unbalanced” port and two “balanced ports”. The balun is a passive and reversible device. Therefore the “unbalanced” port can be used as either an input or an output; likewise the “balanced” ports can be used as inputs or outputs. Baluns are also frequently used as impedance-transforming devices. For historical reasons the most commonly used impedances of the “unbalanced” ports are 50 or 75 Ohms and simple transformation ratios of 1:1, 1:2, and 1:4 are widely used. This creates components with impedances in the ranges of 50:50, 50:100 and 50:200 Ohms for 50 Ohm system impedance and 75:75, 75:150 and 75:300 Ohms for 75 Ohm system impedances.
Furthermore, the report explains information such as insertion loss, analyzer, technique, measurement, and insertion parameters.
