ANAREN BD0205F5050A00

Model BD0205F5050A00
Rev A
Ultra Low Profile 1608 Balun
50Ω to 50Ω Balanced
Description
The BD0205F5050A00 is a low profile sub-miniature balanced to unbalanced
transformer designed for differential input locations on data conversion devices such
as A to D and D to A converters. In an easy to use surface mount package covering
200 MHz to 500 MHz and with CMRR performances over 2x that of the incumbent
wire wound products, this transformer is optimized to offer improved SFDR
management during operation of the data converter device. The BD0205F5050A00
is ideal for high volume manufacturing and is higher performance and smaller form
factor than traditional wire wound transformers. The BD0205F5050A00 has an
unbalanced port impedance of 50Ω and a 50Ω balanced port impedance. This
transformation enables single ended signals to be applied to differential ports on the
data converter devices. The output ports have equal amplitude (-3dB) with 180
degree phase differential. The BD0205F5050A00 is available on tape and reel for
pick and place high volume manufacturing.

Mounting Configuration:
In order for Xinger surface mount components to work optimally, the proper impedance transmission lines must be
used to connect to the RF ports. If this condition is not satisfied, insertion loss, Isolation and VSWR may not meet
published specifications.
All of the Xinger components are constructed from ceramic filled PTFE composites which possess excellent electrical
o
and mechanical stability having X and Y thermal coefficient of expansion (CTE) of 17 ppm/ C.
An example of the PCB footprint used in the testing of these parts is shown below. An example of a DC-biased
footprint is also 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.
If desired, DC biasing through the part may be accomplished by the addition of an inductor on Pin #7. Pins #6 and #8
are DC connected to Pin #7. The inductor should be of sufficient value to provide RF isolation on Pin #7.
