DIGITAL PHASE MODULATOR USING NON-LINEAR AMPLIFIERS AND A RING OSCILLATOR |
摘要 |
The modulator includes an oscillator generating signals, each having a different phase, and a selector receiving digital data. When the digital data received by the selector changes logic state, the selector supplies a first and second plurality of signals generated by the oscillator to first and second non-linear amplifiers, respectively. An adder then adds the output of each amplifier to generate a radio frequency output.
