In the high-performance broadband microwave receiving channel, the mixing circuit comprises a low-frequency band secondary mixing branch and a high-frequency band primary mixing branch;
after 2-18GHz full-band signals pass through the low-noise amplifier, harmonic waves can be generated, but due to the fact that the gain of the first low-noise amplifier of the frequency division circuit is small, the generated harmonic signals are better than-40 dBc. After passing through the power divider and the high-low band-pass filter, the signals respectively enter the high-low band and the low band for processing. Because the low-frequency band signal covers a plurality of octaves, the low-frequency band signal is directly subjected to amplitude limiting amplification, a large amount of harmonic signals can be generated, and the harmonic signals can only be controlled to be about-13 dBc. In order to improve the spurious and harmonic waves of the frequency band, the frequency is up-converted to a millimeter wave frequency band through a first-stage mixer, and then is down-converted to a corresponding intermediate frequency which can be processed by a receiver through a second-stage mixer after filtering, amplitude limiting and amplification, and the harmonic signals can be controlled below-30 dBc by the scheme; the high frequency band does not span an octave, and is directly subjected to amplitude limiting amplification and filtering, and then is subjected to down-conversion to a corresponding intermediate frequency which can be processed by a post-stage receiver through a first-stage mixer, and harmonic signals can be controlled below-30 dBc. Meanwhile, the scheme ensures that the signal stray in the channel is low and the noise is low under the condition that the large dynamic radio frequency signal is compressed to a constant power range.
In the high-performance broadband microwave receiving channel, the gain of a low-frequency-band secondary mixing branch circuit included in the mixing circuit is about 2dB higher than that of a high-frequency-band primary mixing branch circuit. When harmonic signals and fundamental wave signals brought by a front-end microwave link respectively enter the high-band frequency conversion branch circuit and the low-band frequency conversion branch circuit, the rear-end receiver can output fundamental wave signals with amplitudes larger than the amplitudes of the harmonic signals, and the harmonic signal screening function is achieved according to the matching condition of the arrival time of the two signals.
In the high-performance broadband microwave receiving channel, the local oscillation circuit part detects an external input 100MHz signal through a detector and outputs the signal to the comparator, the output level of the comparator is connected to the control bit of the switch, and the internal crystal oscillator is selected to output the 100MHz signal or the external input 100MHz signal as a clock signal of each local oscillation source according to the power of the external input 100MHz signal. When the external 100MHz signal is not accessed, the switch gates the internal crystal oscillator signal, so that the number of external input signal ports is reduced, and the number of interconnection lines among devices is reduced.
In the high-performance broadband microwave receiving channel, the broadband microwave channel adopts a two-channel frequency conversion scheme, the number of channels is small, and a clock signal required by a post-stage receiver is used as a low-frequency-band second-stage local oscillation signal, so that the number of local oscillation sources is reduced. Meanwhile, a proper amplifier is selected, and high-band and low-band frequency conversion branch signals are gradually pushed to saturation output through a multi-stage amplifier, so that the phenomenon that the in-band flatness is poor due to signal power back-off in the saturation output process can be prevented. The invention realizes a miniaturized and high-performance broadband microwave channel.
