1. A radio frequency identification transceiver, comprising:
- a transmitter path, comprising;
a pulse shaper to tunably shape a pulse of a signal to be transmitted in different predefined frequency ranges;
a modulator to modulate the shaped pulse to be transmitted into one of a plurality of predefined frequency ranges;
a receiver path, comprising;
a demodulator to demodulate a received signal from the plurality of predefined frequency ranges;
an in-phase mixer to provide a first differential in-phase signal and a second differential in-phase signal;
a quadrature mixer to provide a first differential quadrature signal and a second differential quadrature signal;
an in-phase amplifier coupled to the in-phase mixer to amplify the first differential in-phase signal and the second differential in-phase signal;
a quadrature amplifier coupled to the quadrature mixer to amplify the first differential quadrature signal and the second differential quadrature signal.
