Would like to request for the sequencing biasing for the hmc998apm5e. In addition, I would like to turn off the PA when it is not in use.
The recommended bias sequence during power-up is as follows:
1. Set VGG1 to −2.0 V
2. Set VDD to 15.0 V.
3. Set VGG2 to 9.5 V.
4. Adjust VGG1 to set Idq=500mA
5. Apply the RF input signal…
5. Apply the RF input signal.
The recommended bias sequence during power-down is as follows:
1. Turn off the RF input signal.
2. Set VGG1 to −2.0 V
3. Set VGG2 to 0 V.
4. Set VDD to 0 V.
5. Set VGG1 to 0 V.
