It is noted here that pin1 and p in3 are NC pins without any internal connections, while pin1, pin4, pin 2 and pin 5 are DC connected internally t ogether. To have T0727J5012AHF function properly, pin 2 and pin 5 are required to be grounded by the mounting footprint . Pin1 Pin4 Pin2 Pin5 Pin1 Pin4

Paralleling four parts of T0727J5012AHF results in the impedance con version 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 moun ting configuration is shown below. It’s noted that the NC pins (pin 3 and pin 6) are connected with the adj acent pins (pin 4 and pin 1) to provide the wide line connection requ ired for the low impedance. Depending on the mount ing substrate and frequency band of application, the value of tuning capacitor may be further optimized.

If this condition is not satisfied, insertion loss, Isolation and VS WR may not meet published specifications. All of the Xinger components are constructed from o rganic PTFE based composites which possess excellen t electrical and mechanical stability. Xinger compone nts are compliant to a variety of ROHS and Green st andards and ready for Pb-free soldering processes. Pads are Gold plated with a Nickel barrier. Series capacitor C1 at pin1 and shunt capacitor C2 at pin4 are required to get the optimum performance . All the input and output pins are DC connected inte rnally together with RF grounds pins. DC bias can b e applied through appropriate RF choke and DC blocking capacitor. An example of the PCB footprint used in the testing of these parts is shown below. In specific designs , the transmission line widths need to be adjusted to the unique dielectric coefficients and thicknesses as well as varying pick and place equipment tolerances. .033 [0.85] 6X .002 [0.05] 6X .010 [0.25] 6X .012 [0.30] 4X .014 [0.35] Plated thru holes to ground 3X Transmission Line Part Orientation (Top View)
