DESCRIPTION
The BGY120A and BGY120B are two-stage UHF amplifier
modules in a SOT482B package with plastic cover. Each
module consists of two NPN silicon planar transistor dies
mounted together with a matching and bias circuit
components on a metallized ceramic substrate.
These modules produce an output power of 1 W into a
load of 50
Ω
with an RF drive power of 5 mW.

Limiting values
BGY120A; BGY120B
This data sheet contains target or goal specifications for product development.
This data sheet contains preliminary data; supplementary data may be published later.
This data sheet contains final product specifications.
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
