Product highlight:
with bypass
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
to set-top box applications. The LNA is housed in a 6-pin SOT363
plastic SMD package.
