BGU7003 400 MHz and 900 MHz application
1. Introduction
The BGU7003 is a wideband low noise amplifier in a plastic, leadless 6 pin extremely thin
small outline SOT891 package. It can be used for various LNA applications up to 6 GHz
such as GPS, satellite radio, cordless phone and E-metering.
The BGU7003 contains 1 RF stage and an internal bias that is temperature stabilized. It
also contains an enable function to shut down the amplifier with a logic signal on the
enable pin.
The BGU7003 is ideal for use where size and low power are most critical. Typical usages
are mobile phones, Personal Digital Assistants (PDA), Personal Navigation Devices
(PND), E-metering and remote controllers.

BGU7003 400 MHz and 900 MHz application
5. Application boards
The BGU7003 400 MHz and 900 MHz band LNA evaluation board simplifies the
evaluation of the BGU7003 in the E-metering application area. The evaluation board
enables testing of the device performance and requires no additional support circuitry.
The board is fully assembled with the BGU7003 IC, including input- and output matching,
to optimize the performance.
A simple feedback path is added to improve its in-band gain flatness as well as improving
stability.
The board is supplied with two SMA connectors for input and output connection to RF test
equipment.
The BGU7003 is designed to operate at 2.5 V with optimal performance, and not to
exceed 2.85 V. When it is used with varying supply voltages (3.3 V to 3.7 V for
E-metering), the enable function is not used and LNA is always on. An enable pin jumper
is installed, which avoids the voltage on the VCC, VEN and RF output pin exceeding
2.85 V.
In this application, the supply voltage is set to 3.7 V which is reduced to 2.5 V by a 215 
voltage dropping resistor.
