Model B0011E75300A00
Rev B
Ultra Low Profile 1008 Balun
75Ω to 300Ω Balanced
Description
The B0011E75300A00 is a low profile sub-miniature balanced to
unbalanced transformer designed for differential inputs and output locations
on next generation analog and digital TV chipsets in an easy to use surface
mount package. The B0011E75300A00 is ideal for high volume
manufacturing and is higher performance than traditional wire wound baluns.
The B0011E75300A00 has an unbalanced port impedance of 75Ω and a
300Ω balanced port impedance. This transformation enables single ended
signals to be applied to differential ports on modern semiconductors. The
output ports have equal amplitude (-3dB) with 180 degree phase differential.
The B0011E75300A00 is available on tape and reel for pick and place high
volume manufacturing.

Figure 2 The Balun with an external capacitor on the
low impedance ground pin. This improves insertion loss
and return loss in the 40-200MHz range over that of the
basic configuration. The capacitor value can be changed
some to get a slightly different performance. A series
capacitor with just pin 4 does NOT produce identical
results as the one just in series with pin 7.

Figure 4 The balun with an external inductor in the low
impedance ground path. This improves the insertion loss,
return loss and balanced performance in the 870-1080MHz
range. This inductance can be realized as a transmission line
(dimensions will depend on the PCB material and ground
plane distance). The added inductance can be used in
conjunction with the external capacitors. When mounted with
high groundplane spacing, part of this inductance comes
automatically from the increased inductance of the typical via
to ground.

Figure 5 Biasing the balanced signals thru the balun.
Dependign on the quality of “C3” the additional capacitor
“C4” may not be needed. The DC-resistance from the bias
point thru to each of the outputs are 10±4Ω. It is important
to keep inductance to a minimum from pin 5 to ground or
balanced performance will suffer. When used with high
groundplane spacings it is recommended to have two or
more via to ground.

Figure 6 Using the balun as an single ended to single ended
impedance transformer (Unun). Pin 5 must be open circuit. It
is recommended to use the 82pF on the low impedance side to
improve the insertion loss and return loss in the 50-200MHz
range. Note that pins 4 & 7 can only be interchanged if pins 9
7 10 are also interchanged, otherwise performance will suffer.
