LW48-793622 QFN Low noise Amplifier

LW48-793622 is a broadband GaN LNA packaged in a standard 4 x 4mm QFN package. The device operates from 2 to 6 GHz and typically provides >22dB of small signal gain, a P1dB of >18dBm and a 1.2dB noise figure. Output third order intercept point is 30dBm.

The GaN device structure also provides a higher input power handling compared to a GaAs device which in some applications will remove the need for an input limiter. Design is internally matched to 50Ω for ease of use.
