SE2438T Block Diagram Y1854 Description The SE2438T is a high-performance, fully integrated RF Front-End Module (FEM) that is designed for Zig Bee®/Smart Energy applications. The SE2438T is designed for ease of use and maximum flexibility, with integrated fully matched input balun, integrated inter-stage matching and harmonic filter, and digital controls that are patible with 1.6 V to 3.6 V plementary Metal Oxide Semiconductor (CMOS) levels. The RF blocks operate over a wide supply voltage range from 2.0 V to 3.6V, which allows the SE2438T to be used in batterypowered applications over a wide spectrum of the battery discharge curve. 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.
