Vertical Balun Mounting Detail
Output 2
(12.5 ohm microstrip)
Output 1
(12.5 ohm microstrip)
Motorola Vertical 860 MHz Balun
Rogers R03010 (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.
Input
(50 ohm microstrip)
Ground
55 mil slot cut
out to accept Balun
