[0098] like figure 2 As shown, the present invention has a high data rate millimeter wave super regeneration receiver including a low noise amplifier LNA, a superbit oscillator SILO, IQ dual mixer Mixer, a first mid-frequency amplifier AMP1, a second mid-frequency amplifier AMP2 and orthogonal coupler Hybrid.
[0099] The radio frequency input signal RFIN is connected to the signal input of the low noise amplifier LNA. The two-phase output terminals of the low noise amplifier LNA are coupled to the two phase inputs of the hyperbupler oscillator SILO, respectively. The orthogonal coupler HYBRID couples the vibration input signal LO to generate an IQ local oscillator signal that is orthogonal to each other. The IQ Dual Mixer Mixer mixes the signal output from the hyperband oscillator SILO and the IQ local oscillator signal output from the orthogonal coupler Hybrid to obtain an I-road intermediate frequency signal and enlarged by the first intermediate frequency amplifier AMP1. And g...
