Description

technical field

[0001] The invention relates to the millimeter wave transceiver technology of the new generation information technology, in particular to a high data rate millimeter wave super regenerative receiver. Background technique

[0002] With the growing demand for high-data-rate wireless communications and the development of broadband circuits in millimeter-wave bands, such as wideband low-noise amplifiers (LNAs, PAs), more and more attention has been paid to ultra-high-speed communications in millimeter-wave bands with moderate spectral efficiency. In recent years, many millimeter-wave receivers with high data rates in CMOS technology have been proposed. However, the realization of high data rate requires higher power consumption, because the gain of a single-stage amplifier in the millimeter-wave band is very limited, and multi-stage amplifier cascading is required to achieve sufficient gain, and the problem of broadband millimeter-wave amplifiers is even more ser...

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...
