Product data sheet
1. Product profile
1.1 General description
The BGU7031 MMIC is a wideband amplifier with internal biasing. It is designed
specifically for high linearity, low-noise applications over a frequency range of 40 MHz to
1 GHz. It is especially suited to Set-Top Box applications.
The LNA is housed in a 6-pin SOT363 plastic SMD package.
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling.
1.2 Features and benefits
Internally biased
Flat gain between 40 MHz and 1 GHz
Noise figure of 4.5 dB
