Large instantaneous bandwidth radio frequency front-end for wireless systems

A radio frequency (RF) front-end, comprising:

• a receiver having:
• an RF input configured to receive an analog RF input signal via an antenna;
• a demodulator comprising:
• a power divider configured to divide the RF input signal into an I-channel component and a Q-channel component,
• a first I-channel mixer configured to down-convert the I-channel component of the RF input signal,
• a first Q-channel mixer configured to down-convert the Q-channel component of the RF input signal, and
• a first phase quadrature device providing phase separation between the down-converted I and Q channel components via the first I-channel mixer and the first Q-channel mixer, respectively;
• a first coding mixer configured to mix a first coding input signal and a signal from a first synthesizer comprising a first center frequency of the RF input signal to generate a first code injected signal;
• a first local oscillator gain amplifier driving the first phase quadrature device based on the first code injected signal or the signal from the first synthesizer;
• a first receiver output providing the down-converted I-channel component to an I-channel of an analog-to-digital converter (ADC);
• a second receiver output providing the down-converted Q-channel component to a Q-channel of the ADC;
• and
• a transmitter having:
• a first transmitter input receiving the I-channel component for an analog RF output signal from an I-channel of a digital-to-analog converter (DAC);
• a second transmitter input receiving the Q-channel component for the analog RF output signal from a Q-channel of the DAC;
• a modulator comprising:
• a second I-channel mixer configured to up-convert the I-channel component for the RF output signal,
• a second Q-channel mixer configured to up-convert the Q-channel component for the RF output signal,
• a second phase quadrature device providing phase separation between the up-converted I and Q channel components via the second I-channel mixer and the second Q-channel mixer, respectively;
• a power combiner configured to combine the up-converted I-channel and Q-channel components into the analog RF output signal;
• a second coding mixer configured to mix a second coding input signal and a signal from a second synthesizer comprising a second center frequency of the RF output signal to generate a second code injected signal;
• a second local oscillator gain amplifier driving the second phase quadrature device based on the second code injected signal or the signal from the second synthesizer;
• and
• an RF output configured to transmit the analog RF output signal via the antenna.
