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. aaa-000915 Fig 1. BGU7003 EVB demo board 2.

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. 5.1 Application circuit schematic (400 MHz band) J1 CON-3PIN J2 CON-2PIN BIASING 1 2 3 1 R1 ENABLE 2 215 Ω 1 2 R2 3.6 kΩ 3 BIAS U1 J5 1 C10 RF-IN CON-SMA-1 2 C11 1 μF ENABLE VCC 5 6 C12 150 pF L1 43 nH C1 150 pF C2 1 μF J6 3 RF-IN 1 VCC 3.7 V J3 CON-3PIN 2 4 RF-OUT 33 nH 220 pF BGU7003 C5 DNP C6 DNP 3 L3 C4 220 pF GND C7 5.6 pF R4 C9 1400 Ω 0.1 μF 2 1 RF-OUT CON-SMA-1 3 C8 3.3 pF aaa-000941 Fig 12.
