The RF input B is symmetrical driven by means of a hybrid for 180° phase shifting, consequently the source
impedance is 100 W. All other impedance for RF tests is 50 W.
The noise figure (NF) is the value for double-side-band measurement.
The intermodulation test (2-carrier-method) which is made on IF-centre
is in reference to a signal-to-IM ratio of 60 dB.
Gain is the ratio of the voltage at the primary coil of L5 to the available voltage at the input.

Normalized to 50 W, measuring range 45 MHz to 750 MHz.
2)
VHF-High and UHF
Normalized to 50 W, measuring range 45 MHz to 1045 MHz. Both inputs are driven symmetrical.
The output impedance of the hybrid is 100 W, the measured levels are then calculated in reference
to 50 W.

Ozone Depleting Substances Policy Statement
It is the policy of TEMIC TELEFUNKEN microelectronic GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems
with respect to their impact on the health and safety of our employees and the public, as well as their impact on
the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as
ozone depleting substances ( ODSs).
The Montreal Protocol ( 1987) and its London Amendments ( 1990) intend to severely restrict the use of ODSs and
forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban
on these substances.
TEMIC TELEFUNKEN microelectronic GmbH semiconductor division has been able to use its policy of
continuous improvements to eliminate the use of ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively
2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency ( EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively.
TEMIC can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain
such substances.
We reserve the right to make changes to improve technical design and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each customer
application by the customer. Should the buyer use TEMIC products for any unintended or unauthorized
application, the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of,
directly or indirectly, any claim of personal damage, injury or death associated with such unintended or
unauthorized use.
