Freescale Semiconductor
Note:
Trim Balun PCB so that a 35 mil tab"
fits into the main PCB slot" resulting
in Balun solder pads being level with
the PCB substrate solder pads when
fully inserted.

Output 1
Freescale has begun the transition of marking Printed Circuit Boards (PCBs) with the Freescale
Semiconductor signature/logo. PCBs may have either Motorola or Freescale markings during the
transition period. These changes will have no impact on form, fit or function of the current product.
