EV1HMC7810ALC3 is a populated, Rogers 4350B based evaluation board. For normal operation, it requires two external supply voltages VDD : 3.3V/150mA at the supply pin VDD and VDD_EXTP/VDD_EXTN. To adjust the gain of HMC7810A VCTL test point can be used. When VCTL is −1.5 V, the gain is maximum, and when VCTL is 0 V, the gain is minimum. In addition the outputs VDET and VREF of the internal peak detector can be monitored from the test point which are labeled VDET and VREF. To implement an external automatic gain control, use an analog attenuator and the features of the peak detector.
