SKY67175-306LF Block Diagram Description 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. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and function...
