Evaluation Board Description

The SE2442L Evaluation Board is used to test the performance of

the SE2442L front-end module (FEM). An Evaluation Board

schematic diagram is provided in Figure 3. A photograph of the

Evaluation Board is shown in Figure 4. A Bill of Materials (BOM)

for the Evaluation Board is provided in Table 8.

Evaluation Board Setup Procedure

Connect Supply

1. Connect J9, J10, and J11 to 50

Ω instruments. Terminate all

unused ports (if applicable) with 50

Ω.

2. Connect the supply ground to Pin 1 of the J4 header.

3. Connect the DC power supply (2.0 to 4.8 V) to pin 2 of the J4

header.

4. Refer to Table 7 for information about selecting the required RF

path.

Measure TX Performance

Apply an RF signal to connector J10 (PA_IN) to monitor the 900 to

930 MHz amplifier performance. Monitor the output power on

connector J9 (ANT).

Measure RX Performance

Apply an RF signal to connector J9 (ANT) to monitor the 900 to

930 MHz RX path performance. Monitor the output signal on

connector J11 (RX_OUT).

CAUTION: Care should be taken not to overdrive the amplifier by

applying too much RF on the input to the device. A

suitable starting input power for the device is

–20 dBm.
