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.

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.

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.

Distortion Considerations:
This balun does NOT contain any ferrite materials and are as such distortion free. Very, very low levels of
distortion can arise from dissimilar metals on the contact pads of the part (Cu-Ni-Au) and from inter-metallic
contaminations within the part.
Power Handling Considerations:
The RF-power handling capability of these baluns depends on the temperature at the mounted interface (base
plate temperature), and whether or not DC-bias is feed through the part. The power handling specified is for
a mounted temperature of 85˚C and no DC-bias and is based on a maximum operating temperature of the
part itself of 125˚C (do not exceed this).
The maximum power handling relates to the dissipated power within the part and is therefore a function of
insertion loss. The insertion loss of this device changes within the specified band. Thus if operated with a
narrowband signal at either band edge (this is what is specified) it will have less power handling than if
operated closer to the center of the band or if operated with a very wideband signal. If signals arrive at the
balun that are out of the specified band, these must be included in the total dissipated power calculation.
However the deteriorating return loss will eliminate some of this power.
The dissipated RF power can be estimated as;

Where:
• in
P is the input power, either on the low impedance side, single ended or the combined differential power
on the balanced side, depending on the feeding direction.
• dB
RL is the return loss in dB associated with the feeding port. I.e. if feed from the balanced side then the
balanced return loss must be used (this however is very similar to the single ended return loss).
• dB
IL is the insertion loss at the operating temperature of the device.
Below the dissipated power is shown at a normalized 1W input power for the balun internal temperature of
125˚C.

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 softboard composites which possess excellent electrical and
mechanical stability having X and Y thermal coefficient of expansion (CTE) of 19 ppm/oC.
An example of the PCB footprint used in the testing of these parts is 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.
