Example Embodiment
[0018] The embodiment of the present invention provides a satellite-borne low-noise 13-channel V-band receiver, such as figure 1 As shown, it includes a polarization selective feed, a V-band low-noise amplifier, a mixer, a frequency separator, an intermediate frequency processing unit, a detection circuit, and a low frequency processing unit;
[0019] The polarization selective feed source receives the noise signal and separates the H polarization component from the noise signal, and the V-band low-noise amplifier is connected to the polarization selective feed source and reduces the input H polarization component. The noise is amplified and output to the mixer. The mixer down-converts the input signal to generate an intermediate frequency signal. The frequency separator is connected to the mixer and separates the intermediate frequency signal into 13 different centers. Frequency and different bandwidth intermediate frequency signals, the 13 intermediate frequency signals are resp...
