描述 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 functional pin descriptions

are provided in Table 1.
