Description
The SKY65378-11 is a high-performance, highly integrated front-
end module (FEM) designed for low power ISM band applications
operating in the 860 to 930 MHz band.
The device is designed for ease of use and maximum flexibility,
with fully matched 50 Ω input and output, and digital controls
compatible with 1.6 to 3.6 V CMOS levels.
The RF blocks operate over a wide supply voltage range from 2.0
to 4.8 V, which allows the SKY65378-11 to be used in battery
powered applications over a wide spectrum of the battery
discharge curve.
The device is provided in a 4 x 4 mm, 24-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.
