SE2431L Block Diagram Sleep mode current: 0.05 A typical Small QFN (24-pin, 3.0 mm x 4.0 mm x 0.9 mm Nickel- Description Palladium-gold NiPdAu plated) package (MSL1, 260C per The SE2431L is a high-performance, fully integrated RF Front-End JEDEC J-STD-020) Module (FEM) that is designed for ZigBee /Smart Energy and 802.15.4 applications. The SE2431L is designed for ease of use and maximum flexibility, with fully matched 50 input and output, integrated inter-stage matching and harmonic filter, and digital controls that are compatible with 1.6 V to 3.6 V Complementary Metal Oxide Semiconductor (CMOS) levels. The RF blocks operate over a wide supply voltage range from 2.0 V to 3.6 V, which allows the SE2431L to be used in battery- powered 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.
