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.

1. All dimensions are in millimeters.
2. Interpret dimensions and tolerances per ASME Y14.5M-1994.
3. Unless specified, dimensions are symmetrical about center lines.
4. Via hole recommendations:
0.025 mm Cu via wall plating (minimum), solder mask on the far side should tent or plug via holes.
5. Stencil recommendations: 0.125 mm stencil thickness, laser cut apertures, trapezoidal walls and rounded
corners offer the best paste release.
6. Solder mask recommendations: Contact board fabricator for recommended solder mask offset and tolerance.
