SE2435L Block Diagram QFN (24-pin, 4 x 4 x 0.9 mm ) NiPdAu plated package (MSL1, 260 C per JEDEC J-STD-020) Description The SE2435L is a high-performance, highly integrated RF front-end module designed for high-power Industrial, Scientific, Medical (ISM) band applications operating in the 860 to 930 MHz frequency range. The SE2435L is designed for ease of use and maximum flexibility with fully matched 50 TX and RX inputs and antenna outputs, 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 SE2435L to be used in battery powered applications over a wide spectrum of the battery discharge curve. The SE2435L is packaged in a 24-pin, 4 x 4 mm Quad Flat No- Lead (QFN) package. A functional block diagram of the SE2435L is provided in Figure 1. Figure 2 shows the pinout for the SE2435L. Table 1 lists the pin assignments and signal descriptions. Figure 2. SE2435L Pinout (Top View) Skyworks Solutions, Inc.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times. Skyworks Solutions, Inc.
