1)Set the network analyzer to measure the low band RF frequency (see Table 5).

2)Set the power range to -35 dBm through -20 dBm, and then set the input power to -30 dBm.

3)Perform a full one-port calibration on port 1 of the network analyzer.

4)Set the network analyzer to measure S11.

5)Connect the EVM RF input, J30, to port 1 of the network analyzer.

6)Measure the RF input return loss.

Low-Band Transmit Mixer: Power Leakage LO In to TX In

Control state: 010100

SEE APPENDIX A: TEST BENCH SETUPS

Test setup Figure 23

The LO In leakage at the TX In port is measured at the low band TX input port J30. Power leakage is a measure of power (in dBm) that couples to the TX port. The measurement is performed using a RF source and a spectrum analyzer.

1)Set the LO source frequency and input power (see Table 5). Connect the LO source to the EVM LO input port, J12.

2)Set the spectrum analyzer to measure at the LO frequency (see Table 5).

3)Connect the TX In Port, J30, to the spectrum analyzer.

4)Measure the LO leakage power.

Low-Band Transmit Mixer: Power Leakage TX In to LO In

Control state: 010100

SEE APPENDIX A: TEST BENCH SETUP

Test setup Figure 24

The Power leakage from TX IN to LO IN is measured at the LO in port, J12. A leakage is a measure of power (in dBm) that couples to the LO IN port. The measurement is performed using a RF source and a spectrum analyzer.
