Embodiment Construction
[0098] Such as figure 2 As shown, a high data rate millimeter-wave super-regenerative receiver of the present invention includes a low-noise amplifier LNA, a super-regenerative oscillator SILO, an IQ dual-way mixer Mixer, a first intermediate frequency amplifier AMP1, and a second intermediate frequency amplifier AMP2 and Quadrature Coupler Hybrid.
[0099] The radio frequency input signal RFin is connected to the signal input terminal of the low noise amplifier LNA. The two-phase output terminals of the low noise amplifier LNA are respectively connected to the two-phase input terminals of the super regenerative oscillator SILO. The quadrature coupler Hybrid couples the local oscillator input signal LO to generate mutually orthogonal IQ local oscillator signals. The IQ two-way mixer Mixer mixes the signal output by the super-regenerative oscillator SILO and the IQ local oscillator signal output by the quadrature coupler Hybrid to obtain an I-channel intermediate frequency s...
