Examine Balanced Twisted Bifilar Lines
This study shows how the wire gauge and number of twists per centimeter used in balanced twisted bifilar transmission lines can impact the characteristic impedance of those lines.
Evaluating Impedance Transformers With A VNA
Some simple calibration techniques applied to a vector network analyzer can aid in making accurate S-parameter measurements on a wide range of impedance transformers.
Designing Wideband RF Impedance Transformers 1
This simplified design approach can lead to low-cost, low-insertion-loss 1:4 impedance transformers capable of operating over bandwidths as wide as three octaves.
