SKY65378-11 Block Diagram Description The SKY65378-11 is a high-performance, highly integrated frontend 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 patible 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....
