Rev
Ultra Low Profile 0606 Balun
50ꢀ to 50ꢀ Balanced
Description
The B0008K5050A00 is a low profile subꢀminiature balanced to unbalanced
transformer designed for differential inputs and output locations on next generation
broadcast applications including tuner chipsets in an easy to use surface mount
package. The B0008K5050A00 is ideal for high volume manufacturing and is
higher performance than traditional wire wound baluns. The B0008K5050A00 has
an unbalanced port impedance of 50ꢀ and a 50ꢀ 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.
NOTE: Currently, only Engineering samples are available for this Part.

* Insertion Loss stated at room temperature (Insertion Loss is approximately 0.15 dB higher at +85 ºC). All performances stated for recommended
operation with external circuitry. **Note that Insertion Loss is calculated as the sum of powers, i.e.10 log[ (S12)2 + (S13)2 ] *** Phase and amplitude
balance can be improved significantly by using an external inductor as described further below on pages 2ꢀ5.
