- •
A filter-less architecture for frequency-doubling microwave signal generator with tunable phase shift is proposed.
- •
Wide bandwidth and tunable phase shift are obtained simultaneously for the generation of microwave signal.
- •
The tunable phase shift is controlled simply by DC regulated power supply.
- •
The system possesses good frequency tunability and multi-wavelength compatibility.
- •
High frequency beyond the operation bandwidth of the modulator and the electrical 90° hybrid can be achieved
