Description

The SE2442L is a high-performance, integrated RF front-end module designed for high-power ISM band applications operating in the 902 to 928 MHz frequency band. The SE2442L 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, allowing the SE2442L 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.
