Abstract
A transceiver circuit including a digital-to-analog converter, a filter coupled to the digital-to-analog converter, a passive mixer coupled to the filter, via a buffer and a multi-stage power amplifier coupled to the passive mixer via a passive amplifier. A transmitter and method for amplifying a RF signal for transmission are also provided.
Claims20
A transceiver circuit comprising:
- a digital-to-analog converter;
- a filter coupled to the digital-to-analog converter;
- a passive mixer coupled to the filter, via a buffer;
- and
- a multi-stage power amplifier coupled to the passive mixer via a passive amplifier.
2 more elements
A transmitter, comprising:
- a digital-to-analog converter;
- a filter coupled to the digital-to-analog converter;
- a passive mixer coupled to the filter, via a buffer, wherein the buffer comprises an inverter-based feedback amplifier;
- and
- a multi-stage power amplifier coupled to the passive mixer via a passive amplifier.
2 more elements
A method for amplifying a RF signal for transmission, comprising:
- converting a digital signal into analog an analog signal, using a digital to analog converter;
- filtering the analog signal, using a low-pass filter;
- mixing, using one or more mixers, the analog signal with a local oscillator signal to produce a modulated RF signal;
- and
- inputting the modulated RF signal to a passive amplifier, wherein an output of the passive amplifier is coupled to a multi-stage power amplifier via an interface.
