Description
The SKY67105-306LF is a GaAs pHEMT and HBT two-stage, 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 HBT output stage provides
high gain, linearity, and efficiency.
The SKY67105-306LF operates in the frequency range of 0.6 to
1.1 GHz. For higher frequency operation, the pin and layout-
compatible SKY67106-306LF (Data Sheet document # 201521)
should be used.
The SKY67105-306LF 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.
