SE2442L Logic Controls (TA = +25 C) Mode Description CSD CTX 0 All off (sleep mode) (Notes 1 and 3) 0 0 1 Rx or Tx bypass mode (Notes 1 and 2) 1 0 3 Tx mode (Notes 1 and 2) 1 1 Note 1: Logic ‘0’ level compliant to V IL as specified in Table 5. Note 2: Logic ‘1’ level compliant to V IH as specified in Table 5. Note 3: All controls must be at logic ‘0’ in order to achieve the specified sleep current. 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. |
