Vertical Balun Mounting Detail
Output 2
(12.5 ohm microstrip)
Output 1
(12.5 ohm microstrip)
Motorola Vertical 660 MHz Balun
Rogers RO3010 (50 mil thick)
PCB Substrate (30 mil thick)
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.

(50 ohm microstrip)
55 mil slot cut

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.
