Due-VectorModulator
Use HMC630LP3E and Arduino Due
Function
- set gain,phase by "-20,90" via serial.
- callibration by "cal,"
- Phase Accuracy Check by "phase,-13"
- Gain Accuracy Check by "Gain,0"
- Auto Cancellation by "cancel,"
- (Calibration, like "cal,Q,1.35,1.36,0.01,1.49" via serial. Need to find minimum gain by searching I/Q. The I/Q is Vmi/Vmq.)
Accuracy
- Phase: < 3 degree OK @-32~--13dB
- Gain: < 2dB @-32~--13dB
