Testing the HMC980LP4E
After biasing the ADPA7002CHIP with the HMC980LP4E at the application nodes, compare the results to Figure 63 to Figure 66 to verify
that the biasing procedure is correct.
Figure 63. IDD vs. Input Power (PIN), VDD = 5 V, Frequency = 32 GHz,
Constant Current Bias and Constant Voltage Bias
Figure 64. POUT vs. PIN, VDD = 5 V, Frequency = 32 GHz,
Constant Current Bias and Constant Voltage Bias
Figure 65. PAE vs. PIN, VDD = 5 V, Frequency = 32 GHz,
Constant Current Bias and Constant Voltage Bias
Figure 66. Output P1dB vs. PIN, VDD = 5 V, Frequency = 32 GHz
