DESCRIPTION
4
Emitter coupled dual NPN silicon RF transistor in a surface
mount 5-pin SOT353 (S-mini) package. The transistor is
primarily intended for applications in the RF front end as a
balanced mixer, a differential amplifier in analog and digital
cellular phones, and in cordless phones, pagers and
satellite TV-tuners.

DEFINITIONS
Data sheet status
Objective specification
This data sheet contains target or goal specifications for product development.
Preliminary specification
This data sheet contains preliminary data; supplementary data may be published later.
Product specification
This data sheet contains final product specifications.
Short-form specification
The data in this specification is extracted from a full data sheet with the same type
number and title. For detailed information see the relevant data sheet or data handbook.
Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
LIFE SUPPORT APPLICATIONS
These products are not designed for use in life support appliances, devices, or systems where malfunction of these
products can reasonably be expected to result in personal injury. Philips customers using or selling these products for
use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such
improper use or sale.
