General Description

SAC3099Q3 packs 36 dB of gain into an air cavity QFN low noise amplifier for 0.8 to 2.5 GHz. Built on GaAs MMIC, it holds a 0.6 dB typical noise figure (0.8 dB max), 16 dBm output P1dB and 33 dBm OIP3.

Bias is +5 V at 70 mA, flatness is ±1 dB, and both ports are matched to 1.5:1 VSWR. Footprint is 3 x 3 x 1.1 mm around a 1.25 x 1.25 mm die. With that much gain, an L-band or lower S-band receiver can often skip a second gain stage.
