This new product line can make a major contribution to space savings in tuner block circuits as
balun transformers for unbalance-balance conversion of antenna inputs, for products such as tuner
ICs for terrestrial digital broadcasts. In addition, these components can also be used as balun
transformers for analog TV tuner circuits.
These new products are free of all substances controlled by RoHS regulations.
Mass production of the wire wound type commenced in November 2006 at the rate of 4 million
units per month, while mass production of the film type is set to commence in December 2006, at
3 million units per month. Sample price is set at 20 yen per unit for each type.
[Background]
The antenna inputs of tuner ICs use balanced input signals, but the output of the antenna is
unbalanced. For this reason, balun transformers are generally used to convert unbalanced signals
to balanced signals. However, due to their construction, conventional balun transformers are
largeapproximately 5 mm x 5 mm. Since this has presented a hindrance to enabling more
compact, space-saving tuner modules, it became necessary to develop more compact balun
transformers.

[Terminology]
" Balun transformer
A part that converts signals between balanced and unbalanced. It is also known as a
balanced-unbalanced converter. The name balun is derived from the first letters of the two
words, balanced and unbalanced.
" Balanced
A method of transmitting signals using two signal lines. One line carries the source signal; the
other carries a signal of opposite phase (antiphase).
