Above schematic is to demonstrate how to convert the 50 Ohm to 3 Ohm using T0727J5012AHF. Paralleling four
parts of T0727J5012AHF results in the impedance conversion of 12.5 Ohm to 3 Ohm. Cascading another
T0727J5012AHF in series provides a total impedance conversion of 50 Ohm to 3 Ohm. An illustrative mounting
configuration is shown below. It’s noted that the NC pins (pin 3 and pin 6) are connected with the adjacent pins (pin 4
and pin 1) to provide the wide line connection required for the low impedance. Depending on the mounting substrate
and frequency band of application, the value of tuning capacitor may be further optimized.
