1.1 General description
The BGU7045 MMIC is a 3.3 V wideband amplifier with bypass mode. It is designed
specifically for high linearity, low-noise applications over a frequency range of 40 MHz to
1 GHz. It is especially suited for Set-Top Box applications.
The LNA is housed in a 6-pin SOT363 plastic SMD package.
1.2 Features and benefits
