Annotation for characteristics section  
Attenuation of WCDMA signal (“Powertransferfunction”, αWCDMA) is determined by  
Sds21(f)HRRC(f – fCarrier) 2df  
fCarrier according to 3GPP TS 25.101 (e.g. for WCDMA Band 2 Passband, fCarrier ranges from  
1852.4 MHz (lowest Tx channel) to 1907.6 MHz (highest Tx channel)). HRRC(f) is the transfer  
function of the root-raised cosine transmit pulse shaping filter according to 3GPP TS 25.101 with  
the following normalization:  
HRRC(f) 2df= 1

Important notes  
The following applies to all products named in this publication:  
1. Some parts of this publication contain statements about the suitability of our products for  
certain areas of application. These statements are based on our knowledge of typical  
requirements that are often placed on our products in the areas of application concerned. We  
nevertheless expressly point out that such statements cannot be regarded as binding  
statements about the suitability of our products for a particular customer application.  
As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar  
with them than the customers themselves. For these reasons, it is always ultimately  
incumbent on the customer to check and decide whether an EPCOS product with the  
properties described in the product specification is suitable for use in a particular customer  
application.  
2. We also point out that in individual cases, a malfunction of electronic components or  
failure before the end of their usual service life cannot be completely ruled out in the  
current state of the art, even if they are operated as specified. In customer applications  
requiring a very high level of operational safety and especially in customer applications in  
which the malfunction or failure of an electronic component could endanger human life or  
health (e.g. in accident prevention or life-saving systems), it must therefore be ensured by  
means of suitable design of the customer application or other action taken by the customer  
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained  
by third parties in the event of malfunction or failure of an electronic component.  
3. The warnings, cautions and product-specific notes must be observed.  
4. In order to satisfy certain technical requirements, some of the products described in this  
publication may contain substances subject to restrictions in certain jurisdictions (e.g.  
because they are classed as hazardous). Useful information on this will be found in our  
Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more  
detailed questions, please contact our sales offices.  
5. We constantly strive to improve our products. Consequently, the products described in this  
publication may change from time to time. The same is true of the corresponding product  
specifications. Please check therefore to what extent product descriptions and specifications  
contained in this publication are still applicable before or when you place an order.  
We also reserve the right to discontinue production and delivery of products. Conse-  
quently, we cannot guarantee that all products named in this publication will always be  
available. The aforementioned does not apply in the case of individual agreements deviating  
from the foregoing for customer-specific products.  
6. Unless otherwise agreed in individual contracts, all orders are subject to the current  
version of the “General Terms of Delivery for Products and Services in the Electrical  
Industry” published by the German Electrical and Electronics Industry Association  
(ZVEI).  
7. The trade names EPCOS, BAOKE, Alu-X, CeraDiode, CSMP, CSSP, CTVS, DeltaCap,
