EVALUATION AND TEST
To configure the EV1HMC8362LP6G and EV1HMC8364LP6G
for the first time, follow Step 1 through Step 6 outlined in the
Evaluation Board Setup Procedure section.
The frequency vs. tuning voltage listed in the following steps are
specific to the EV1HMC8362LP6G, but the same process is
applicable to the EV1HMC8364LP6G. The frequency range and
performance are different.
1.
Enable the variable power supply, and adjust the tuning
voltage to 8.45 V.
2.
If the EV1HMC8362LP6G is configured correctly, a signal
at approximately 13.5 GHz with approximately 0 dBm to
2 dBm of output power appears on a spectrum analyzer or
signal source analyzer. Refer to Figure 4.
3.
Remove the bias for the buffer amplifier (VCB), which
results in the output power decreasing by approximately
28 dBm. Refer to Figure 5.
4.
Finally, use the signal source analyzer to measure the phase
noise. Refer to Figure 6.
