The ADRF5301-EVALZ is shipped assembled and tested. Figure
4 shows a basic setup diagram to measure the scattering parame-
ter response of the ADRF5301 . To complete the test setup and
verify the operation of the ADRF5301-EVALZ, perform the following
steps:
1. Connect the GND test point to the ground terminal of the two
3.3 V DC power supplies.
2. Connect the VDD test point to the voltage-output terminal of the
3.3 V DC power supply.
3. Connect the CTRL test point to the voltage-output terminal
or ground terminal of the other 3.3 V DC power supply. The
ADRF5301 can be configured in different modes by connecting
the CTRL test point to 3.3 V or 0 V, as shown in Table 3 .
4. Connect the RFC, RF1, and RF2 ports to a calibrated network
analyzer.
5. Turn on the 3.3 V DC power supply connected to the VDD test
point.
6. Turn on the 3.3 V DC power supply connected to the CTRL test
point.
7. Measure the scattering parameters.
