SKY67175-306LF

1.5 to 3.8 GHz Two-Stage, High-Gain Low-Noise Amplifier

Please note: SKY67175-306LF is being discontinued and is not recommended for new designs. The suggested replacement are SKY67179-306LF, SKY67180-306LF



The SKY67175-306LF is a two-stage, GaAs pHEMT low-noise amplifier (LNA) with active bias and high linearity performance. The pHEMT front end of the device provides an ultra-low noise figure (NF) while the cascode output stage provides high gain, linearity, and efficiency.

With excellent thermal performance, the SKY67175-306LF is rated for operation up to +105 °C.

The SKY67175-306LF is provided in a 4 x 4 mm, 16-pin Quad Flat No-Lead (QFN) package.
