This is accomplished by biasing Vg1 into its pinchoff region - typically -1V to -2V. By adjusting the Vg1 bias, the device will operate as a doubler or tripler. Vg2 may also be adjusted to minimize the levels of unwanted harmonics. The plot shows the performance of HMC283 operated as a doubler with Vg1 = -1V and the remaining gate voltages (Vg2, 3, 4) set to -0.15V. In this condition the amplifier draws 310mA at 3.5V drain bias (Vdd) and provides +5dB to -5dB conversion loss dependent upon the output fre- quency. By connecting the Vdet port to a 10k Ohm resistor and monitoring the voltage, a B.I.T. circuit can be created to monitor changes in the device output power. This circuit is extremely well compensated for temperature variations as shown in the first plot. The detected voltage does change with frequency and the second plot shows its variation.
